    • 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.
    • 被称为“安静开关”的摇杆式电气开关包括具有彼此以小角度的两个相对的接触表面的可手动按压的摇杆,摇臂从该摇臂上取决于摇臂凸轮终止的摇臂。 位于摇杆和摇臂凸轮之间的滑块通过摇臂的侧向运动而前后移动,并打开和关闭一对或多对触点。 摇杆运动由与摇臂凸轮接合的摇杆凸轮叶片弹簧控制,该弹簧具有由摇摆凸轮移动的凸轮廓以减慢开关,锁定摇杆并提供其它期望的效果。 摇杆凸轮弹簧容纳在比自身更长的弹簧室中,允许摇杆凸轮弹簧浮起。
