Abstract
A miniature ratchet type push button activated electrical switch having a mainspring and an auxiliary spring wherein spring rates, spring lengths and spring orientations are selected such that a substantial depression of the push button is required before electrical continuity is broken in a closed circuit. This configuration additionally serves to reduce the amount of audible noise generated by the switch during the ratcheting operation.
