<p>A rotor of a switch actuator includes a selector cam having a serrated cam surface which mates with the serrated cam surface on a selector cam follower. The selector cam follower is slidably retained within an actuator sleeve which surrounds the rotor and the cam follower is forced into mating engagement with the selector cam by a bias spring. The force of the spring is translated by the serrated cam surfaces into a torque which provides a snap-action when the rotor is rotated between its selectable positions.</p> |
