Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a push button switch, and more specifically,
The present invention relates to a push button switch that operates a switch part by moving a working plate via a plunger by operating a push button.

(Problems to be solved by the conventional technology and device) As a push button switch of this kind, a push button switch can be in an operating state only while a push button is being pressed, and a push button switch from this operating state. It is known that the operating state can be retained (locked) by rotating the.

That is, the former push button switch has a movement guide mechanism formed between the operating plate and the base body, and is configured to be movable only in the movement guide direction (axial direction) of the movement guide mechanism when the push button is operated. When the button is released, it can be moved in the opposite direction. In short, prevent the operating plate from rotating so that it will not lock the switch in the operating state even if the operating plate rotates and contacts somewhere on the base body and the operation is released. , The quality of this type (momentary type) is guaranteed.

On the other hand, in the latter push button switch, in addition to the former push button switch, in order to lock the operating state of the switch portion when the operating plate is rotated, the locking portion of the rotated operating plate (for example, , Notches) are formed.

With the above-mentioned configuration, the two types of push button switches can have the same operating plate, but cannot have the same base.

The present invention has been made in view of these circumstances, and an object of the present invention is to provide a push button switch that can manufacture two types of push button switch components in common and enables cost reduction by mass production.

(Means for Solving the Problems) In the present invention, in order to achieve the above-mentioned object, a switch portion, a base body mounted on the switch portion, a plunger movably supported by the base body, and the plunger. With push buttons and actuation plates fixed to the front and rear ends of
Further, a movement guide mechanism that engages with each other is formed on the operation plate and the base body, and the operation plate is moved along the guide direction of the movement guide mechanism via the plunger by the push operation of the push button, and the switch portion is turned on. In the push button switch to be operated, the operation plate is provided with a rotation blocking piece for blocking the rotation of the operation plate in a detachable manner, and the push button is operated while the rotation blocking piece is detached and used on the base body. When the switch portion is operated and the push button is further rotated, a locking portion that locks a part of the rotated operation plate to keep the switch portion in an operating state is provided.

(Operation) When the operating plate is used as it is, the operating plate can only move in the axial direction of the plunger by the rotation blocking piece,
Since it cannot rotate, the switch can be operated only when the push button is being pressed (momentary type switch).

On the other hand, when the operating plate is used by disconnecting the rotation blocking piece, it can be rotated by the push button after pressing the push button to activate the switch part, and thereby the operating plate is locked to the locking part. And the switch part can be maintained in an activated state (lock type switch).

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an exploded perspective view of essential parts of a push button switch according to the present invention, and FIG. 2 is a bottom view showing a relationship between an operating plate and a base body.
3 to 4 are diagrams corresponding to FIG. 2 for explaining the operation in different usage states, and FIG. 5 is a perspective view showing the overall configuration.

1 to 2 and 5, a push button switch 1 comprises a base body 3 on which a switch portion 2 is mounted, and a plunger 4 supported by the base body 3 so as to be axially movable and rotatable. A push button 5 and a substantially rectangular actuating plate 6 fixed to the front and rear ends of the plunger 4.

A groove 7 is formed on one of the short sides of the operating plate 6, and a cut 8 is formed from the groove 7 to one of the long sides, and an arcuate groove 9 is formed on the other short side. Is forming. The outside of the cut 9 forms a rotation blocking piece 8a.

On the other hand, the base body 3 is mainly composed of a horizontal portion 10 and vertical portions 11 and 12 extending downward from both ends of the horizontal portion 10. The inner corner portion of the horizontal portion 10 and the vertical portion 11 is guided to move to the groove 7. The guide pillar 13 is formed, and the engaging portion 14 is formed at the inner corner of the horizontal portion 10 and the vertical portion 12. The groove 7 and the guide column 13 constitute a movement guide mechanism.

In addition, 15 and 15a are screw shafts for attaching the base body 3 to the other end (for example, the operation panel of the instrument), 17 is a mounting screw hole of the switch portion 2, and 18 is a mounting hole. 19 is the mounting hole 18
Is a screw that penetrates through the switch portion 2 and is screwed into the mounting screw hole 17, and 20 is a terminal of the switch portion 2.

In this way, the push button base 1 lowers the actuation plate 6 via the plunger 4 by the push operation of the push button 5, and actuates the switch unit 2. In this case, since the groove 7 of the actuating plate 6 moves by sliding on the guide column 13 of the base body 3, the actuating plate 6 is not caught by the base body 3 in the middle, and the switch portion 2 can be securely operated.
Operate. When the operation of the push button 5 is released, the groove 7 slides on the guide column 13 in the operating plate 6 by the biasing spring (not shown), so that the switch portion 2 can be securely held without being caught by the base body on the way. Can be deactivated, ensuring the function of a momentary type contact.

Next, in particular, as shown in FIGS. 3 to 4, when the notch 8 position of the actuating plate 6 is manually folded and the rotation blocking piece 8a is separated and removed, the push button 5 is pushed to remove the case shown in FIG. Similarly, the operating plate 6 is lowered to operate the switch unit 2. At this time, when the push button 5 is rotated, as shown in FIG. 4, the operating plate 6 is allowed to rotate because the rotation blocking piece 8a is removed, and a part 6a of the operating plate 6 is locked. The operation plate 6 is prevented from rising (locked) even if it is locked to the portion 14 and the hand is released from the push button 5, and the operating state of the switch portion 2 is maintained to ensure the function of the lock type contact.

As described above, the switch can be switched from the momentary type to the lock type by cutting at the notch 8 position of the operating plate 6 and separating and removing the rotation blocking piece 8a, and eventually both types of parts have exactly the same specifications. Therefore, mass production is possible and cost reduction is achieved.

(Effect of the Invention) As described above, according to the present invention, the switch can be switched from the momentary type to the lock type by simply disconnecting a part of the actuation plate, whereby both types of switches are manufactured as the same part. It enables mass production and brings down costs.
