Abstract

769,105. Switch covers. MIDLAND ,ELECTRIC MANUFACTURING CO., Ltd. Oct. 4, 1955 '[July 29, 1954], No. 22148/54. Class 38(5) In a combined switch/fuse an operating lever 8 projects through a slot 7 in a removable cover 6 and a resilient or spring- urged member 9 also projects through the slot and overlaps the cover, so that when the switch is "on" the lever 8 is adjacent the member 9 and the cover cannot be removed. When the lever is moved to the "off" position an operator may deflect the member 9 sideways to permit the removal' of the cover. The member 9, which may be formed of, or covered with insulating material, is shaped to facilitate the replacement of the cover. A spring-loaded slidable bolt 10 engages a movable part of the switch when the cover is off and so prevents operation of the switch.
