Abstract

717,068. Switch cases; indicators for switches. REVO ELECTRIC CO., Ltd. May 26, 1953 [May 23, 1952], No. 13073/52. Class 38(5) The dolly 10 of a tumbler switch 9 projects through an aperture 11 in the hinged or removable cover 5 of a switch box 4 and is associated with a slidable bolt 14 adapted to engage with a latch plate 15 on the inside of the cover 5 to prevent the opening of the cover unless the switch is " off." The bolt 14 has an aperture which closely embraces the dolly and is slidably mounted between the face of the switch and a bracket 12 which has an aperture 13 similar to that in the cover 5. The dolly 10 has a bevelled outer edge on which the word " off " is visible when the switch is in the off position and the word " on engraved on the front of the switch is uncovered by the bolt 14 when the dolly is moved to the on position.
