ABSTRACT:
A rocker-type electrical switch of the kind known as a "quiet switch" includes a manually depressible rocker having two opposed contact surfaces at a small angle to each other from which rocker depends a rocker arm terminating in a rocker cam. A slider positioned intermediately of the rocker and the rocker cam is moved back and forth by side-to-side movements of the rocker arm and opens and closes one or more pairs of contacts. Rocker movement is controlled by a rocker cam leaf spring engaging the rocker cam which spring has a cammed profile traversed by the rocker cam to slow the switch, lock the rocker and provide other desirable effects. The rocker cam spring is housed in a spring chamber longer than itself, allowing the rocker cam spring to float.
