On the other hand, when the switch body 1 is replaced due to its life, it is not necessary to replace the operation unit 10 side.

[0014]

1 is a side sectional view showing a first embodiment of a waterproof switch of the present invention. The switch body 1 is composed of a tact switch in which the movable portion 2 moves in the vertical direction.
The switch body 1 is arranged on a printed circuit board 3 provided inside a housing of an electronic device or the like. An opening hole 5a having a predetermined diameter is formed in the front surface portion 5 of the housing so as to correspond to a position on the movable portion 2 of the switch body 1.

An elastic film 7 having a predetermined thickness is provided on the surface portion 5.
The elastic film 7 covers the opening hole 5a and has a waterproof function for the inside of the housing. Therefore, the elastic body film 7 is adhered to the surface portion 5 around the opening hole 5a with a waterproof double-sided tape or an adhesive.

The tip of the movable portion 2 of the switch body 1 is located in contact with the lower surface of the elastic film 7 (strictly, a slightly distant position). Therefore, depending on the height of the switch body 1. The position of the printed circuit board 3 with respect to the surface portion 5 is set.

On the elastic film 7, an operating portion 10 for an operator to operate a switch is provided. As shown in the drawing, the operating portion 10 is formed by molding an elastic body into a protrusion shape, and the protruding operating protrusion 11 can be formed in various shapes corresponding to a push button type key top. On the bottom of the operation unit 10, an operation projection 12 facing the movable unit 2 and having a predetermined step is formed.

A surface panel 15 on which the switch function and the like are displayed is provided on the surface portion 5. Front panel 15
An opening portion 15a corresponding to the outer diameter of the operation protrusion 11 of the operation portion 10 is formed in the opening, and is detachably fixed to the surface portion 5 with a screw. And the front panel 1
By means of 5, the operation portion 10 has the engagement piece 13 portion retained and retained between the surface panel 15 and the surface portion 5. Here, as shown in the figure, the elastic operation unit 10 fixes the attachment of the front panel 15 with a pressing force enough to press the locking piece 13.

In this waterproof switch, the switch changeover operation is performed by pushing down the operation protrusion 11 of the operation portion 10. Figure 2
As shown in the operation diagram of FIG. 5, since the operating portion 10 is formed of an elastic body, when a pushing force from above acts on the operating projection 11, it is transmitted as a downward moving force of the operating projection 12 and the elastic body is moved. The movable part 2 of the switch body 1 through the membrane 7
Can be moved downward to switch the switch.

The waterproof switch is operated by the operation unit 10.
Is completely separated from the switch body 1 through the elastic film 7. Therefore, even if the operation protrusion 11 of the operation unit 10 exposed to the outside is damaged, the switch body 1 is waterproof by the elastic film 7, and the waterproof property can be maintained.

When the operation unit 10 is replaced,
This can be done by simply removing the front panel 15, which can then be replaced without touching the switch body 1. On the other hand, when the switch body 1 is replaced, this can be done by opening the housing and removing the printed circuit board 3 on which the switch body 1 is mounted from the inside, and at this time, the switch body 1 can be replaced without touching the operation portion 10 side. In this way, by the structure in which the operation unit 10 and the switch body 1 are separated, this can be done without operating the other when exchanging one, so the exchanging work can be facilitated.

FIG. 3 is a side sectional view showing another example in which the entire operation portion 10 of the waterproof switch is formed of a rigid body. When the operation protrusion 11, the operation protrusion 12, and the locking piece 13 of the operation portion 10 are formed of a rigid body, as shown in the figure, the surface portion 5
A spacer or the like is provided between the front panel 15 and the front panel 15 and is mounted with a predetermined gap. As a result, the entire operation unit 10 can be moved in the vertical direction, the entire operation unit 10 is moved by the pushing of the operation protrusion 11, and the operation protrusion 12 is also moved downward, so that a predetermined switch can be switched. The operation projection 11 and the locking piece 13 that contacts the elastic film 7 may be made of an elastic body.

FIG. 4 is a side sectional view showing still another modification of the above embodiment. In this example, the surface portion 5 of the housing is formed to be slightly thick, and the step portion 5b is formed in the opening portion 5a opened in the surface portion 5. At the step portion 5b portion, the collar portion 17 that is locked to the step portion 5b is provided.
A spacer 17 having a is provided. The spacer 17 is provided between the lower surface of the elastic film 7 and the movable portion 2 of the switch body 1. The spacer 17 has a height such that the upper surface 17b is in contact with the lower surface of the elastic film 7 and the lower protrusion 17c is in contact with the movable portion 2 of the switch body 1 as shown in the figure, without applying a pressing force from above. To form. In this state, a predetermined gap is formed in the vertical direction between the collar portion 17a and the step portion 5b, and the gap moves up and down for the switch operation.

In this waterproof switch, when the operation protrusion 11 is pushed downward, the lower protrusion 17 is inserted through the spacer 17.
c operates the movable portion 2 of the switch body 1 via the elastic film 7. Since the lower protrusion 17c of the spacer 17 projects downward from the lower end of the surface portion 5 only when it is pressed downward, the upper end position of the movable portion 2 of the switch body 1 is the lower surface position of the surface portion 5. It can be provided below.

Therefore, the switch body 1 can be replaced by taking out the mounted printed circuit board 3 from the direction sliding in the front or depth direction shown in the drawing. Regarding the support structure of the printed circuit board 3 in the housing 4, by forming a groove portion 4a for supporting an end portion of the printed circuit board 3 inside the housing 4, the printed circuit board 3 is provided along the groove portion 4a. Can be easily replaced from the front side or the direction sliding in the depth direction as shown in the drawing.

Next, FIG. 5 is a side sectional view showing a second embodiment of the waterproof switch of the present invention. In the figure, the same components as those in the above embodiment are designated by the same reference numerals. This waterproof switch is a seesaw type switch. The operation unit 20 is formed of an elastic body, and has two operation protrusions 21 on the upper portion.
Projections a and 21b are formed, and two operation projections 22a and 22b are correspondingly formed on the lower part. An arcuate turning projection 22c is formed in the center.

Openings 5a and 5b are formed in the surface plate 5 of the housing in correspondence with the positions of the two operating projections 22a and 22b, and the switch bodies 1a and 1b are formed in the openings 5a and 5b, respectively.
The movable parts 2a and 2b of b are located. As described above, in the second embodiment, the switch body 1 is configured to switch between the tactile switches while the operation portion 20 provides the operation feeling of the seesaw type switch.

In this waterproof switch, when either one of the operation protrusions 21a and 21b of the operation portion 20 is operated in the rotating direction, one of the operating protrusions 21a and 21b in the rotating direction is centered on the rotating protrusion 22c. Is urged downward.
Then, the corresponding movable pieces 2a, 2 via the elastic film 7
When b is pressed downward, either of the switch bodies 1a and 1b is switched. With the above structure, the durability of the conventional seesaw type switch was 100,000 times, but by using the tact type switch bodies 1a and 1b that operate in the vertical direction, the switching performance of 10 million times can be obtained. It becomes possible to improve the durability significantly.

Even with this waterproof switch, the operating section 20
Since the switch bodies 1a and 1b are separated from each other through the elastic film 7, damage to one does not immediately affect the other, and waterproofness can be maintained. Further, in this embodiment, the two switch bodies 1a and 1b are used, but since the operation portion 20 is formed of the elastic body, it is possible to simultaneously press the two operation protrusions 21a and 21b. Therefore, in the electrical switching circuit that receives the switching output of the switch bodies 1a and 1b, it is judged that the switch switching is superior, and the other of the switch bodies 1a and 1b, which is switched on a first-come, first-served basis, is delayed, Alternatively, when they are pressed simultaneously, it is desirable to set in advance that they are processed as a control input for safety such as special operation (e.g., emergency stop).

Next, FIG. 6 shows a modified example of the second embodiment. In this example, like the conventional seesaw type, the operation of the operation unit 20 is surely switched for each side. For this purpose, at least the operation protrusions 21a and 21b of the operation portion 20 may be formed of a rigid body, and the protrusion heights of the operation protrusions 22a and 22b may be arranged so as to be spaced apart from the elastic film 7 by a predetermined distance. As described above, the core member 25 may be inserted inside while molding the whole body with an elastic body.

The core member 25 is formed of a rigid body such as a metal plate which is inserted between the operating protrusions 21a and 21b and the operating protrusions 22a and 22b in the lateral direction. It is possible to configure so that when the switch is rotated in one of the illustrated directions, only the switch main body in the rotation direction (for example, the switch main body 1a is operated by operating the operation protrusion 21a). The core member 25 may be configured to project in the same shape at the rotation protrusion 22c.

Next, FIG. 7 is a side sectional view showing a third embodiment of the waterproof switch of the present invention. Also in the figure, the same components as those in the above embodiment are designated by the same reference numerals. This waterproof switch is a toggle type switch. The operation unit 30
It is formed of an elastic body, and the operation protrusion 21 is formed on the upper portion thereof, and the two operation protrusions 32a and 32b are formed on the lower portion thereof. An arcuate turning protrusion 32c is provided at the center.
Are formed.

Openings 5a and 5b are formed on the surface plate 5 of the housing in correspondence with the positions of the two actuating projections 32a and 32b, and the movable portions 2a and 2a of the switch bodies 1a and 1b are respectively formed. 2b is located. As described above, in the third embodiment, the switch body 1 is configured to switch between the two tact switches while the operation portion 30 provides the operation feeling of the toggle type switch.

In this waterproof switch, when the operating protrusion 31 of the operating portion 30 is operated in either one of the turning directions, any one of the operating protrusions 31a and 31b in the turning direction is lowered about the turning protrusion 32c. Be urged by. And ...
Corresponding movable pieces 2a, 2b are pressed downward via the elastic film 7 to switch one of the switch bodies 1a, 1b. With the above configuration, the conventional toggle type switch has a durability of 100,000 times, but by using the tact type switch bodies 1a and 1b that operate in the vertical direction, the switching performance of 10 million times can be obtained. It becomes possible to improve the durability significantly.

Even with this waterproof switch, the operating section 30
Since the switch bodies 1a and 1b are separated from each other through the elastic film 7, damage to one does not immediately affect the other, and waterproofness can be maintained. In addition, although the two switch bodies 1a and 1b are used in this embodiment, since the operation portion 20 is formed of an elastic body, the operation protrusion 31 is pushed downward instead of being rotated, and at the same time, the two switches are formed. The main bodies 1a and 1b are switched. Therefore, even in the waterproof switch of the third embodiment,
An electrical switching circuit for receiving the switching output of the switch bodies 1a and 1b is provided to judge the superiority of the switching of the switches or, when pressed at the same time, perform a special operation (for example, an emergency stop) for safety control. It is desirable to set in advance to process as an input.

Next, FIG. 8 is a diagram showing a modification of the second embodiment. In this example, like the conventional toggle type, the operation of the operation unit 30 reliably switches each side. For this purpose, at least the operation protrusion 31 of the operation portion 30 is formed of a rigid body, and the operation protrusions 32a, 32
The protrusion height of b may be configured so as to be spaced apart from the elastic film 7 by a predetermined distance.
The core material 35 may be inserted inside.

The core material 35 includes the operation projection 31 and the operation projection 3.
2a, 32b is formed of a rigid body such as a metal plate which is inserted in a lateral direction, and when the operating portion 30 is rotated in one of the illustrated directions, the switch main body in the rotating direction is formed. Only the switch body 1a can be switched (for example, when the switch body 1a is rotated leftward in the drawing). The core member 35 may also be configured to protrude in the same shape at the rotation protrusion 32c.

In the waterproof switches of the respective types described in the first to third embodiments, various types of switches are arranged side by side on the front panel 15 of a single casing constituting the electronic equipment. It can also be applied in some cases. In this case, the front panel 15 has each type (that is,
The push button type, see-see type, and toggle type operation units 10 and 2
It is sufficient to provide 0 and 30. In addition, various operation units 10 and 2
Even when 0 and 30 are provided, each locking piece 13, 23 and 33
By continuously molding the parts, it becomes possible to mold a plurality of operating parts with a single elastic body, and manufacturing and replacement at the time of breakage can be facilitated.

The elastic film 7 may also be a single sheet formed over each switch portion. Further, according to the present invention, the switch bodies 1 are all the same tact switch 1 even when various types of operation units 10, 20, 30 are provided on the front panel 15.
The quality of each switch,
The durability can be the same. At the same time, since the switch main body 1 can be provided on the single printed circuit board 3, the entire switch main body 1 side can be replaced, and the replacement work can be facilitated.

Next, FIG. 9 shows a fourth embodiment of the present invention, and is an exploded perspective view showing a remote controller in which the various types of switches are arranged in parallel. FIG. 10 is a vertical sectional view of the remote controller. The remote controller 40 operates a crane provided at a remote place by operating a switch. A push button type switch and a switch having a pseudo seesaw type function are provided on the surface portion 5 of the remote controller 40. An opening 5a having the stepped portion 5b is correspondingly formed at the location where each switch is arranged, and a spacer 17 having a flange 17a is provided in each opening 5a.

On the surface portion 5, a single elastic film 7 formed corresponding to the shape of the surface portion 5 is provided so as to cover it, and the housing is adhered with a waterproof double-sided tape 54 or the like. Waterproof the inside of the body 4. On the elastic film 7, an operation elastic body 50 having a function equivalent to that of the push button type operation section 10 and the general seesaw type operation section 20 is provided. The operation elastic body 50 is formed by integrally molding an elastic body such as rubber, and the push button type operation protrusion 1 is provided on a flat locking piece 53.
1, seesaw type operation protrusions 21a and 21b are formed to project.

The seesaw type operation protrusions 21a and 21b
As shown in FIG. 10, a side surface is formed with an inclined surface that is inclined in the same direction, and the shape is different from an integral type such as a general seesaw type (FIG. 5). However, this pseudo seesaw-type operation unit 20 is formed with the two operation protrusions 21a and 21b adjacent to each other, as is the case with a general-purpose seesaw-type switch. The reason is that the switch operation in one direction and the other direction, such as the direction, is selectively switched by operating the same finger.

Then, as shown in FIG. 10, operation projections 12, 22a, 22b are formed on the lower surface of the operation elastic body 50 so as to correspond to the positions of the operation projections 11, 21a, 21b. In addition, inside the housing 4, each operating protrusion 1
Tact type switch bodies 1 are provided corresponding to the positions 2, 22a, 22b, the switch bodies 1 are mounted on a printed circuit board 3, and each movable portion 1a is in contact with a position directly below a spacer 17.

The front panel 15 is provided on the elastic body 50 for operation. The front panel 15 has a two-layer structure, and the lower presser plate 15a is fixed on the front plate 5 with screws 55, and elastically presses the locking piece 53 of the operating elastic body 50 from above to lock it. . On the upper nameplate 15b,
Characters, pictograms, etc. indicating the operation contents of each switch are displayed. Between the two operation protrusions 21a and 21b used in the seesaw-type operation portion 20 of the holding plate 15a, an intermediate locking portion 15aa is formed so as to project upward at about the height of the operation protrusions 21a and 21b. This allows the operator's finger to
The belly portion is abutted and locked to this intermediate locking portion 15aa,
The operation protrusion 21 whose tip position is one from the ball part of the operator's finger
a, and the front position from the ball portion of the operator's finger comes into contact with the other operation protrusion 21b.

Regardless of which of the operating protrusions 21a and 21b is operated, the ball portion of the operator's finger is always locked by the intermediate locking portion 15aa, and the operation can be performed stably. . In both operation directions by the operator's finger, only one of the operation projections 21a and 21b can be pressed from above with the intermediate locking portion 15aa as the center, as shown by the arrow in the figure. 21b both have the shape of an inclined surface which is inclined in the same direction, so that both operation projections 21a and 21b cannot be pushed at the same time, and the crane can be controlled only in one desired direction. The safety and reliability of the operation that can operate is obtained.

According to this waterproof switch, even if the electronic device is provided with different types of switches,
The operation part and the switch body are roughly separated from each other via an elastic film, and the operation protrusion of the operation part forms a shape for each type on a single elastic body. The switch body can be configured with the same tact switch, which reduces the number of parts.
Can be shared. At the same time, even if it is necessary to replace either the operation unit or the switch body, since one is separated from the other, only the replacement target needs to be replaced, and the replacement work can be extremely facilitated. . Further, the switch body 1 is composed of all the same tact switches, and the operating force for the switch body 1 is only in the vertical direction, so that the durability of the switch body 1 can be obtained up to 10 million times. The seesaw-type switch of the above has obtained extremely high durability for 100,000 times.

The printed circuit board 3 provided with the switch body 1 has a structure in which both ends are engaged and held in the groove 4a inside the housing 4, and the lid 4b at the end of the housing 4 is opened. Thus, the printed circuit board 3 can be attached and detached in this direction. As described above, the spacer 1 is also used in this embodiment.
With the configuration using 7, the upper end of the movable portion 2 of the switch body 1 is positioned below the lower surface position of the surface portion 5, and the printed circuit board 3 can be easily moved in this insertion / removal direction.
