ABSTRACT:
A load break switch and interlock assembly is housed in a cabinet with a door. The switch assembly is oriented 90.degree. from a normal position along the backwall of the cabinet and is located on a sidewall. The switch handle protrudes through the front of the cabinet. The handle is horizontally oriented to interfere with the door when the switch is closed thereby preventing the door from being opened. When the switch is open, the handle is vertically oriented and does not interfere with the door.
