When the rocker paddle is pushed in, the paddle urges the semi-rigid driver means to rotate a cam means in a first, clock wise direction, or a second, counter clock wise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and determines its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by a spring to pivot back to its initial position.

The safety switch may be used in severely cold environments.
