Patent

CA 2180165

A double-pole single-throw switch has a pair of spaced stationary contacts (52, 56) adapted for carrying current to individual circuits. A cantilevered, torsionally flexible, electrical current carrying arm (34) has a pair of correspondingly spaced moveable contacts (42,44) mounted on the free end and disposed adjacent the stationary contacts. A toggle spring actuator (30) has one reaction end (32) engaging a slot (38) in the end of the electrical current carrying arm for effecting relative lost motion movement and impacting the sides (40) 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.
