〔Example〕

Below is the first example of applying the present invention to a sliding switch device.
Examples will be described with reference to FIGS. 1 to 6.

Reference numeral 1 denotes a horizontally elongated container body, which is open at the top and has guide steps 2 and 3 formed along the longitudinal direction at the front and rear ends of the bottom, respectively. Furthermore, a large number of engagement claws 4 and 5 are formed adjacent to each other along the longitudinal direction at the bottom of the container body 1, and the engagement claws 4 are arranged diagonally toward the right. The engaging pawl 5 has a sawtooth shape directed upward, and conversely, the engaging pawl 5
It has a sawtooth shape that is oriented diagonally upward as it goes to the left. Fixed contacts 6, 6 are disposed at the front and rear ends of the bottom of the container body 1 along the guide steps 2, 3. Reference numeral 7 denotes a plastic holder having a substantially rectangular shape, which is housed within the container body 1 and placed on the guide steps 2 and 3 so as to be slidable in the left and right direction. This holder 7 has rectangular mounting holes 8 and 9 formed therein, and a spring receiving hole 1 in the center thereof.
0 is formed, and the spring receiving hole 10
The upper part thereof is formed into a knob portion 11 by protruding upward. A compression coil spring 13 is interposed between the deep part of the spring receiving hole 11 and the contact plate 12 in the lower part thereof, and the movable contacts 14, 14 of the contact plate 12 are connected to the fixed contacts 6, 6. It is designed to make elastic contact with the Reference numerals 15 and 16 indicate knobs, which have a rectangular cylindrical shape with a closed top surface, and are prevented from coming out upwardly in the mounting holes 8 and 9 of the holder 7, respectively, so that the knobs are rotated vertically in a direction perpendicular to the sliding direction of the holder. It is inserted so that it can be moved in the direction. And these knobs 1
Compression coil springs 17 and 18 are interposed between 5 and 16 and the bottom wall of the holder 7, respectively.
Normally, the knobs 15 and 16 are biased to their original positions in which substantially the upper halves of each protrude upward from the guide hole 20 of the cover 19 attached to the upper opening of the container body 1. Reference numeral 21 denotes a plastic working claw which is pivotally mounted on the knob 15 so as to face the engaging claw 4 from above, and is normally applied with rotational force in the direction of arrow 23 by a torsion coil spring 22. The rotational force thereof is regulated by a regulating wall 15a formed within the knob 15, so that the operating pawl 21 is held in its original position in a hanging state. Reference numeral 24 designates a plastic operating claw that is pivotally mounted on the knob 16 so as to face the locking claw 5 from above, and is normally applied with a rotational force in the direction of the arrow 26 by a torsion coil spring 25. The rotating force is regulated by a regulating wall 16a formed within the knob 16, thereby holding the working claw 24 in its original position in a hanging state.
In addition, in FIGS. 2, 4 to 6, the fixed contact 6 is shown in the center for convenience of explanation.

Now, 27 is a moderation mechanism, which will be explained below. That is, 28 is a moderation part formed on the inner surface of the front wall part of the vessel body 1, and this has many triangular peaks and troughs 28a, 28 along the longitudinal direction.
8b, and each trough 28b corresponds to each step position of the holder 7 as described later. Reference numeral 29 denotes a storage section formed on the front wall of the holder 7, which has a concave shape with an open front surface. A steel ball 31 is disposed in this storage portion 29 via a compression coil spring 30, and the steel ball 31 is moved by the spring force of the compression coil spring 30 to the trough 28b of the moderation portion 28.
It has come into contact with the ball.

Next, the operation of this embodiment will be explained. Now, when one of the knobs 15 and 16 held at the original position above is pressed, for example, the knob 15 is pressed, and the working claw 21 is lowered together with the knob 15.
As shown in FIG. 4, the tip of the working claw 21 comes into contact with the engaging claw 4, and when the knob 15 is further pressed, the working claw 21 comes into contact with the engaging claw 4, as shown in FIG.
is rotated in the opposite direction to the arrow 23 direction against the spring force of the torsion coil spring 22 while engaged with the engagement claw 4, and the working claw 21 presses and moves the holder 7 to the right. . As the holder 7 moves to the right, the steel ball 31 moves from one valley 28b over the adjacent peak 28a on the right side to the next valley 28b and comes into elastic contact with it. As a result, further movement of the holder 7 to the right is prevented. Thereafter, when the pressing operation force on the knob 15 is released, the knob 15 returns and rises due to the spring force of the compression coil spring 17, and the operating pawl 21 is twisted and rotated back in the direction of arrow 23 due to the spring force of the coil spring 22. As a result, the knob 15 and the operating claw 21 return to their original positions as shown in FIG. 6, and therefore the holder 7 is more engaged in the state shown in FIG. 6 than in the state shown in FIG. This results in a step to the right by one pitch of the dowel 4. Thereafter, by repeating the pressing operation and release of the knob 15 in the same manner, the working claw 21 sequentially engages and disengages from a large number of engagement claws 4, and the holder 7 is sequentially moved to the right. Each time, the steel ball 31 climbs over the peak 28a and reaches the next valley 2.
It comes into elastic contact with 8b. Then, as the holder 7 moves forward, the movable contacts 14, 14 of the contact plate 12 selectively come into contact with the fixed contacts 6, 6, thereby performing a switch switching operation. Note that when the knob 16 is pressed, the tip of the working claw 24 comes to engage with the engaging claw 5, and in this case, the engaging claw 5 has an inclination opposite to that of the engaging claw 4. Therefore, when the holder 7 is stepped to the left and the holder 7 is moved to the left by one pitch of the engaging claw 5, the steel ball 31 is positioned to the left of one valley 28b. Next valley part 2
Move to 8b and come into contact with it. Moreover, if the holder 7 is moved to the right or left by holding the knob 11 of the holder 7 with fingers, the holder 7 can be moved to the right without the working claw 21 or 24 engaging or disengaging from the engaging claw 4 or 5. It can be slid in the direction or leftward by the required pitch, and therefore can be operated in the same way as a conventional sliding switch device.

As described above, according to this embodiment, the following effects can be obtained. That is, knob 15 or 1
Holder 7 equipped with movable contacts 14, 14 by repeating the pressing operation on 6 and its release
Since the switch is made to advance in steps, it is possible to perform small-scale operations, and therefore, unlike conventional sliding switch devices, there is no possibility of overrun due to excessive operating force. Further, the container body 1 is provided with a large number of serrated engagement claws 4 and a large number of serrated engagement claws 5 that are inclined in the opposite direction.
and 16 are provided with working claws 21 and 24 that engage and disengage the engaging claws 4 and 5, respectively.
The holder 7 can be moved either to the right or to the left, making it extremely convenient to use.
Furthermore, when the knobs 15 and 16 are in their original positions above, the working claws 21 and 24 are separated upward without contacting the engaging claws 4 and 5, so that the knobs 15 and 16 are held in their original positions. Knob 1 in non-pressed state
1, the holder 7 can be slid to the right or to the left by the necessary pitch. Therefore, it can be used when it is desired to slide the holder 7 to a relatively distant target position all at once. , resulting in excellent operability. Furthermore, since the moderation mechanism 27 is provided between the container body 1 and the holder 7, when the knob 15 or 16 is pressed, the holder 7 is moved rightward or leftward by one pitch of the engaging claws 4 or 5. When the steel ball 31 is moved from one trough 28b to the next trough 28b located on the right or left side, the holder 7 is prevented from moving further to the right or left. Therefore, each time the knob 15 or 16 is pressed, the holder 7 can be reliably advanced by one pitch of the engaging claws 4 or 5, and therefore the holder 7 cannot be moved by more than one pitch. This has the advantage of preventing so-called skipping, and since the holder 7 is held by the steel balls 31 coming into elastic contact with the troughs 28b at each step position, the holder 7 is held even though the knobs 15 or 16 are not pressed. There is no such thing as 7 being moved unnecessarily.

Furthermore, since the knobs 15 and 16 are configured to move together with the holder 7, it is easy to recognize the operating position. There is no need to provide a complicated display mechanism.
