ABSTRACT:
An improved two position control switch includes a spring biased pivoting armature with a projecting cantilever spring wire. The spring wire can be flexed in a direction transverse to the pivoting movement of the armature. The spring wire flexes to cooperate with a cam track thereby retaining the armature in one of two stable positions. Switching between positions occurs in response to pulse signals to the armature coil.
