Abstract
A disconnect switch includes a crossbar assembly having an arm at each of its ends which rotatably fastens the assembly to a frame for swinging motion around a pivot axis. Three movable contact assemblies are carried by the crossbar between a closed position in which their line side ends engage stationary contacts and an opened position in which their line side ends are disengaged. Stationary connectors aligned along the pivot axis engage the load side ends of the movable contact assemblies at all positions of the crossbar.
