Abstract
A push button switch of the invention has base rubber having actuator portions, a resin molded portion attached to the base rubber, and a permeable film formed on the surface of the resin molded portion. More preferably, a flange portion of the film is disposed so as to avoid a region just above thick portions such as base plate supported portions of the base rubber. A push button switch capable of preventing peeling of coating or the like and intrusion of water can be therefore provided. A push button switch and a switching device which have satisfactory touch and can be thinned can be provided.
