ABSTRACT:
A double-pole single-throw switch has a pair of spaced stationary contacts adapted for carrying current to individual circuits. A cantilevered, torsionally flexible, electrical current carrying arm has a pair of correspondingly spaced moveable contacts mounted on the free end and disposed adjacent the stationary contacts. A toggle spring actuator has one reaction end engaging a slot in the end of the electrical current carrying arm for effecting relative lost motion movement and impacting the sides of the slot for causing rapid making and breaking and a wiping motion of the contacts. The spring engages the slot midway between the contacts to permit angular movement to accommodate misalignment of the stationary contacts.
