ABSTRACT:
The push button switch according to the invention comprises a push button, a press member operated by the push button, a stationary contact member secured to a substrate and a movable contact member operated by the press member. One end of the movable contact member is shaped to engage the stationary contact member with a line contact whereby positive and low resistance contact is ensured. Further, a cushion member in the form of a resilient pad or spring is interposed between the press member and the push button for alleviating the shock created when the push button is depressed.
