Zusammenfassung: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.
