Abstract

A rotary switch having a multiple throw axial cam rotor and operatively aligned detent teeth. One held stationary contact spring spider has plural radially disposed axially-movable cam follower switch contact arms engaging the axial cam, and also has plural detent springs engaging the axial detent teeth. A base has stationary contacts to be selectively engaged by the switch contacts, and a journal post upon which the rotor is rotatable. An externally accessible shaft upon the rotor has a surrounding resilient "O" ring. A housing sealed to the base and bearing upon the "O" ring seals the switch. The switch may be fabricated in DIP size and contact configuration.
