Abstract
A push button switch comprises a key top having a recess and a resilient member provided so as to surround the recess of the key top. The resilient member has a projected portion extending therefrom in the direction away from the recess of the key top, and at least the end of the projected portion is formed of conductive material. A contact member is secured to a base plate in opposed relationship with the projected portion. A holder member holds the key top in such a manner that the projected portion of the resilient member is normally spaced apart from the contact member but engages the contact member upon depression of the key top.
