Abstract
A miniature ratchet type push button activated electrical switch wherein a first electrical contact is caused to sweep across and briefly contact a second electrical contact upon depression of a push button to transmit an electrical pulse. The rotation is driven by the free expansion of a spring upon depression of the push button beyond a preselected depth, and therefore results in a pulse of uniform duration independent of how quickly the push button is depressed or how long it is held in its depressed state.
