ABSTRACT:
A momentary push-button switch wherein a movable contact piece is made of an elastic and conductive metal sheet by incurvating the latter and providing a pair of coupling portions on its sides in parallel with the depressing direction of the switch, and the coupling portions are bent to increase their rigidities against a pressing force. A switching tactility based on the inversion of the movable contact is clearly developed.
