Push button switch

摘要

A momentary pushbutton switch has a circular actuating button with a downwardly extending center post. The post is in continuous contact with a center cantilevered leg of a spring contact member. The spring contact member also has side arms that are joined at opposite ends to respective end portions. One end portion is fixed to one terminal on a base member and the opposite end portion is free and spring biased above a stationary contact on the base. Depression of the actuaing button forces the cantilevered leg and free end downwardly toward a stop on the base. The free end then engages the stationary contact, closing the switch contacts. The base and contacts are specially formed to make assembly simple and error free.
