接片。 1 and 2 are sectional views showing the internal state of an embodiment of the switch according to the present invention before the pressing operation and at the time of the maximum pressing operation, respectively, and FIG. 3 shows the plate-like switch shown in FIG. 1 and the sliding state. FIGS. 4A to 4G are perspective views showing a part of the rod in correspondence, and sequentially outline the movement of the sliding rod and the deformation of the leaf spring member when the push button is pressed and when the pressing operation is released. FIG. 5 is a diagram showing changes in operating force and changes in electrical resistance with respect to the stroke of the push button. FIG. 6 is a schematic diagram of another embodiment of the switch of the present invention, and FIG. 7 is a diagram showing a conventional switch.

Claims

[Scope of utility model registration request]

A switch consists of a case with a built-in switch part and an operating member that is slidably supported by the case and is operated by pressing. It deforms elastically to apply a force that resists the movement of the operating member, and when the operating member moves to a predetermined position, it disengages from the locking part of the operating member and releases the force, allowing the pressing operation of the operating member. A first leaf spring portion that provides a sense of moderation, and a resilient restoring action of the first leaf spring portion when the first leaf spring portion is disengaged from the locking portion of the operating member displaces the switch portion. A switch having a structure in which a leaf spring member integrally having a second leaf spring part for operating the switch is provided inside the case.
