摘要	PURPOSE: To prevent a poor operation of switch owing to the hooking of a switch operating member and the like by setting the distances between plural switching members variable through the elastic deformation of a rib-form connection which is formed integrally to the plural switch operating members. CONSTITUTION: A push-button switch 11 consists of an elastic formation material and is formed integrally. Connections 11b are formed into two ribs opposing each other whose widths are small enough responding to the respective lengths, and the lengths are larger than the straight distance between key tops 11a and 11a, formed curving in about a circular arc to the inner direction the both ribs approach each other. Moreover, the connections 11b are formed to make not only the widths small enough to the lengths, but also the thicknesses small and thin sufficiently. And the distance and the pitch between the key tops 11a and 11a is set variable through the elastic deformation of the connections 11b. In such a composition, a hooking of the key tops 11a in the restoration after they are depressed can be prevented, and a secure operation of the switch can be guaranteed. COPYRIGHT: (C)1989,JPO&Japio
