ABSTRACT:
An electric switch comprising a plurality of electrically conductive resilient strips secured to an electrically insulating base member and a supporting member for supporting the strips in such a manner that these strips extend substantially in parallel with each other at a given distance and store resilient force in a direction opposite to that of an operational force. An electrical contact is made by displacing one of the resilient strips toward the other strip against the stored resilient force. In a preferred embodiment prior to securing the strips to the base member the strips have been bent in the direction opposite to the acting direction of the operational force.
