Abstract

PROBLEM TO BE SOLVED: To ensure high assembling workability via the application of a simple structure, allow parts to be used in common for both pushing and pulling operations, and obtain a click feeling at the time of operation by providing an operation shaft between a front plate and a rear plate in a clamped state. SOLUTION: The rear end of an operation shaft 4 is inserted in an insertion hole 3A of a rear plate 2, and the front end thereof is inserted in an insertion hole 3 of a front plate 1. Then, the front plate 1 and the rear plate 2 are mounted and fixed, thereby clamping the operation shaft 4 in a state free from looseness. Thereafter, a substrate 8 with switches 9 mounted thereon are fixed to the rear plate 2. When the front end of the operation shaft 4 is pressed, a part near the center of a thin part 6 is deflected approximately to an inverted- V shape, and the base of the thin part 6 comes in contact with the rear plate 2. As a result, the rear end of the operation shaft 4 pushes the switches 9. Then, the operation shaft 4, when released from a pressing force, is reset to an original position, due to the elasticity of the thin part 6.
