Switch and contact modules therefor

摘要

Switches for a variety of circuits for different purposes are formed by using similarly designed contact modules each having a module case including a normally closed or normally open contact mechanism and a plunger for operating this contact mechanism, a single actuator having two end parts and being biased so as to rotate around a supporting axis, this actuator undergoing a rotary motion if a force is applied to one of its end parts so as to operate the plunger of an associated one of the contact modules with at least one of the end parts, a switch case that includes the contact modules and the actuator, and a push button for applying a force on one of the end parts of the actuator from outside the switch case.
