ABSTRACT:
A switch device wherein components including an actuator bar and a spring can be installed one after another from above an upper opening of a casing, enabling automation of an assembling operation. The switch device includes a conductor plate mounted for rocking motion within a casing to cause switching of the switch device, and a switch operating member mounted for pivotal motion on the casing and including an actuator element and an operating element snap-coupled to each other. The actuator element has a vertical through-hole perforated therein while the operating element has formed thereon a depending projection which is received in the through-hole of the actuator element. An actuator bar and a compression spring are received in the through-hole of the actuator element such that the compression spring abuts at opposite ends thereof with an end of the projection of the operating element and an end of the acutator bar so that it normally urges the actuator bar to resiliently contact with the conductor plate for operation of the latter.
