Abstract: A switch guard for preventing accidental actuation of a control switch is disclosed. The switch guard includes a rigid wall structure comprising a pair of side walls and a pair of end walls arranged to accommodate positioning of the control switch therein, each of the pair of end walls including at least one opening formed therein. The switch guard also includes a mating feature provided at each of the end walls of the wall structure, with each mating feature being a separate component from the rigid wall structure and being configured to selectively translate through the at least one opening formed in the respective end wall between a first position and a second position to secure the switch guard about the control switch.

Abstract: A switch comprises a first and second contacts, a plunger, a toggle bar, and a spanner. A preferred trip lever arrangement is used in which a trip lever transfers an actuating force from the plunger to the toggle bar, and the toggle bar is caused to move farther than the plunger to provide a short trip point. Swing arms that are acted upon through a series of rigid body force transfers allow an operator to manually force welded contacts to be broken in the event that the contacts become welded to a spanner or other components of the switch assembly.
