Abstract

968,276. Indicators for switches. ENGLISH ELECTRIC CO. Ltd. Feb. 1, 1961 [Feb. 20, 1960], No. 6057/60. Heading H2B. A switch in a casing 10 has an operating handle 17 coupled to an ON/OFF indicator 20 visible through a window 21 in a hinged door 11. A second indicator combined with means for locking the switch in the off position comprises a slide 24 mounted on the inside of door 11 as shown. When slide 24 is moved by means of a lip 28 to locate a ball catch 26 in a hole 27 in the slide, the end 30 (bearing a suitable legend) is interposed between the indicator 20 and window 31, and when the door 11 is closed a lug 29 on slide 24 overlies a lug 22 on indicator 20 to prevent closure of the switch. A conventional cylinder lock 12 is provided on door 11. Should the door 11 be closed with the indicator 30 in the "locked off" condition and the switch " on " the lug 23 of indicator 20 engages lug 29, Figs. 3 to 5, not shown, to force slide 24 back to the inoperative position, thus allowing the " ON " indication to show through window 21.
