Push switch and method of manufacturing the same

摘要

Provided are a push switch capable of effectively suppressing a position deviation or a wobble of a slider caused by errors of mold sizes as well as reducing mold cost, and a method of manufacturing the same. The push switch includes a slider (3) which is supported by a tubular case (2) to reciprocate and is pushed to be operated. Contact inclined surfaces (33a to 36a) of contact convex portions (33 to 36) of the slider (3) come in contact with restriction inclined surfaces (22a to 25a) of restriction concave portions (22 to 25) of the tubular case (2), respectively, the slider (3) upon retreating is returned to a predetermined non-operation position. In addition, the slider (3) is molded by injection-molding a resin material having a higher thermal contraction coefficient and a lower melting temperature than the resin material of the tubular case (2) in a cavity using the tubular case (2) as a part of a mold.
