Abstract
There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes semi-rigid spiral wound driver means having a conical end coupled to be driven by the rocker paddle. 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 rocker paddle of the switch is not located within a frame and has a surface along its vertical axis of positive first differential and zero second differential, comprised of a combination of splines which extend between points of varying distances from a datum plane.
