Abstract
805,310. Switch handles. BRUSH ELECTRICAL ENGINEERING CO. Ltd. March 19, 1957 [March 20, 1956], No. 8691/56. Class 38 (5). A mechanism for preventing movement of an oil switch operating handle over its full range (ON - OFF - EARTH) inadvertently, comprises a plate A having two parallel slots 2, 3, a slidable shutter B movable to block one or other of the slots, a rotor C, D, connected to the switch contacts and having two sockets 5, 6, one per slot, each capable of receiving a detachable operating handle E. With the shutter in its left-hand position, the handle can be placed in socket 5 and the switch can be moved between ON and OFF positions. When the handle is in the OFF position, it can be removed from socket 5, the shutter can be slid to the right, and the handle can then be placed in socket 6 and the switch can be moved between OFF and EARTH positions. The shutter and the handle can be padlocked in each position.
