By pressing one side of a pressing body 22 attached to the upper part of the switch operating member 20, the switch operating member 20 swings in the direction of the arrow X-Y using the support portion 21 as a fulcrum. There is a compression spring 2 inside the switch operating member 20.
3 is housed therein, and is configured to be pressed toward the conductor plate 25 by a driver 24 biased by this compression spring 23. A plate spring 31 having a substantially M-shape as a whole is placed on the conductor plate 25. It is sandwiched between the upper surface of These leaf springs 31 and the conductor plate 25 are configured to swing in a seesaw shape with the center terminal 26 as a fulcrum, and the conductor plate 25
Movable contacts 27a and 27b are attached to both ends of. Further, 30a and 30b are fixed contacts arranged corresponding to these movable contacts 27a and 27b,
28 and 29 indicate terminals connected to these fixed contacts 30a and 30b, respectively.

のである。
In the above type of switch device, when the switch is switched, the free end of the leaf spring 31 slides outward on the conductor plate 25 while resisting the biasing force of the compression spring 23. The sudden change in the biasing force of the compression spring 23 is absorbed by the deformation of the spring 31. Therefore, the impact force when one movable contact comes into contact with the corresponding fixed contact is alleviated.
This effectively prevents chattering caused by the separation of the conductor plate 25 from the center terminal 26.

とがあつた。 However, since the deformation direction of the leaf spring 31 and the swinging direction of the conductor plate 25 are the same, that is, the leaf spring 31 and the conductor plate 25 deform or swing along a plane parallel to the paper plane of FIG. Because of this structure, if the compression spring 23 or the leaf spring 31 fluctuates from the set value or if the switch operation member 20 is suddenly switched, the leaf spring 31 absorbs the sudden change in the biasing force of the compression spring 23. As a result, when the movable contact contacts the corresponding fixed contact, the conductor plate 25 and the leaf spring 3
1 rebounded together, causing chattering.

能であつた。 In addition, in such a switch device, an attempt has been made to use a leaf spring 31 for preventing chattering as the compression spring 23, but in the above type of switch device, the leaf spring 3 is entirely M-shaped.
1 must be brought into contact with the conductor plate 1 at the swing fulcrum position, the compression spring 23 is absolutely necessary to facilitate the reversal movement of the conductor plate 1, and the switch operation member 20 and the drive body 24 are It was impossible to integrate them and simplify the structure of that part.

As detailed above, the present invention is configured so that the elastic piece fixed to the conductor plate makes contact with the center terminal by utilizing the elastic force that acts in the direction of pinching the center terminal. Therefore, even if the conductor plate is separated from the center terminal due to the rebound when the movable contact contacts the fixed contact, the electrical connection between the conductor plate and the center terminal via the conduction plate will not be maintained. It is maintained reliably and the occurrence of chattering can be completely prevented. In addition, a leaf spring is installed on the conductor plate so as to maintain a predetermined distance from the top surface of the conductor plate, and the driving body is configured to slide on the top surface of the leaf spring.
By using the elastic force in the direction perpendicular to the plate surface of the leaf spring, the compression spring that was required in the past to urge the driver toward the conductor plate can be omitted, simplifying the structure of the switch device. can.
