ABSTRACT:
A miniature ratchet type electrical switch exhibiting a reduced audible noise level operation having a damping spring incorporated in a ratchet mechanism switch construction for reducing the forces otherwise exerted on the ratcheting mechanism by a main spring during the camming and seating operation of the components with the force exerted by the damping spring opposing the force exerted by the main spring, thereby reducing the noise associated with this function, and including a reprofiled tooth and cam configuration for preventing the jamming of the moving parts. Incorporation of these features in a ratchet mechanism type electrical switch in which the main spring completes the switch circuitry yields a reliable and aesthetically improved switch function with a high current carrying capacity. Switch constructions in both single-pole, double-throw and single-pole, single-throw versions are disclosed.
