摘要： A push switch having a mount base 11 made of a heat resisting and insulating material and having a recess 11a in the top surface thereof, the recess 11a receiving a plurality of contact terminals 12a, 13a disposed such that contact portions constituting at least a pair of conductor circuits are arranged in the recess, a curved push spring 14 having an inverting function and disposed in the recess 11a, and an operating portion through which the push spring 14 is operated so as to turn the switch on and off. A flexible heat resistant film 15 constituting the operating portion is attached to the mount base in a manner such as to cover the entire area of opening of the recess. With this dust proof and semi-hermetic arrangement, it is possible to prevent invasion by dusts and other foreign matters which are strictly to be kept away from the switch. The invasion by flux and molten solder also is avoided so that the switch can be manufactured by new methods such as solder dipping.
