Abstract
An electrical switch construction having a housing carrying a fixed contact and a snap blade having a contact to be snapped relative to the fixed contact as the blade is moved relative to the housing to provide a switching function with the fixed contact. A generally C-shaped actuator has opposed ends disposed on opposite sides of the blade, one end of the actuator being interconnected to the blade to cause snap movement thereof upon movement of that one end of the actuator in one direction relative to the housing. A compression spring is disposed between that one end of the actuator and the housing to tend to oppose movement of that one end of the actuator in that one direction. A motion transmitting arrangement is carried by the housing and is operatively associated with the other end of the actuator whereby movement of the other end of the actuator toward the blade by the motion transmitting means in the one direction causes an initial flexure of the actuator between the ends thereof before the one end is moved sufficiently in that one direction to cause the blade to snap relative to the housing.
