Abstract
A depression actuated switch which is suitable for achieving a reduction thickness and which does not easily malfunction even when an end depressing operation is performed thereon includes: a driving member 4 having a depressing portion 4a and a mounting portion 4b which are connected together by an elastic portion 4c that is elastically deformable during operation; a sheet-like flexible member 2 to the lower surface of which the mounting portion 4b of the driving member 4 is attached; a cushion member 3 which is positioned so as to surround the driving member 4, to the upper surface of which the sheet-like flexible member 2 is glued and which is more liable to be elastically deformed than the sheet-like flexible member 2; a click spring 5 which is arranged below the depressing portion 4a of the driving member 4 and which generates a tactile click feel when it flips over; and a membrane switch 6 arranged below this click spring 5 and which effects conduction between contacts by the click spring 5 which has flipped over.
