ABSTRACT:
An electric switch which translates a pivotable toggle motion to a rectilinear contact engaging and breaking movement, including an actuator assembly and a contact assembly which are clamped together during assembly with a face plate. The actuator assembly facilitates assembly by capturing a pivotable operating lever between a halo which adapts the actuator assembly to a face plate, and a halo adapter which adapts the actuator assembly to the contact assembly. The contact assembly includes a movable contact carrier to which a cam is fixed. The cam includes a recess which defines spaced lateral stops, and a cam surface which slopes axially inward between the spaced lateral stops, with the operating lever having a cam actuator end which enters the recess and rides on the cam surface.
