Abstract
A cam actuated switch permitting rotation in one direction with snap action and in the other direction without snap action. When the cam is rotated in one direction, the switch contacts are opened rapidly by a substantially radial step on the cam surface and a spring arm which presses a cam follower, disposed on another spring arm, against the surface. When the cam is rotated in the other direction, the cam follower is permitted to be displaced axially from the step by the other spring arm and thereby aligned with a ramp which moves both spring arms radially outward to close the switch contacts.
