Abstract

A switch assembly including an actuator assembly operable to magnetically latch a switch in a closed position, where the actuator assembly includes a cup member coupled to the drive rod opposite to the switch and an opening spring positioned within the cup member and being held in compression when the switch is latched closed, and where the cup member includes a central opening. The switch assembly further includes a scissor link having a first leg and a second leg pivotally attached at a pivot point, where one end of the first and second legs extend into the central opening and are rigidly attached to the cup member and an opposite end of the first and second legs extend through the cover, and where pulling the link away from the actuator assembly breaks the magnetic latch and opens the switch.
