Abstract

In an electrical switch construction having a movable switch blade carried in the chamber of a housing and being moved between operating positions thereof by movement of an actuator, an overtravel spring engaging against the blade and the actuator for moving the blade in unison therewith as the actuator moves in unison therewith in one direction to a predetermined position relative to the housing and for thereafter preventing further movement of the blade in the one direction even though the actuator is further moved in that one direction beyond the predetermined position. A plate is carried by the housing and has a pivot arm bent therefrom at an angle relative thereto for providing a pivot for a part of the switch blade. The housing has a slot for holding the plate immediately adjacent the bent angle of the pivot arm.
