ABSTRACT:
A rotary switch includes a keylock housing having a collar disposed therein and a rotor disposed in a switch case housing to provide an internal labyrinth geometry. The collar includes a plurality of spaced mechanical stops to provide multiple mechanical travel options determined by the orientation with which the collar is disposed in the housing. Thus the stop collar may be disposed in the keylock housing in a plurality of different orientations with each of the orientations providing a keylock mechanism disposed in the keylock housing with a corresponding mechanical travel. The internal labyrinth geometry provided by the rotor-switch case housing assembly increases the electrical path length through which an electric charge must travel. Thus, the rotor-switch case housing assembly provides the rotary switch with protection from electrostatic discharge.
