DIMMER SWITCH A switch including a plunger adapted for reciprocal motion in a housing. A substantially rigid first wiper is fixedly mounted to a cam for selective rotation in the housing, One end of the plunger engages the cam for altering the position of the first wiper relative to an electrical contact. The first wiper and electrical contact are arranged to define a make-before-break switching action. A cam follower provides a detent action of the cam which facilitates high speed switching independent of the actuation speed of the plunger. A second wiper is interposed between opposed ends of the plunger and selectively actuates a flash-to-pass feature. |
