Abstract
436,172. Indicators for switches. PENDERGAST, F. R., SHEERMAN, S. E., and UNITED ELECTRICAL CO. (COOLEX), Ltd., Chester Street, Birmingham. May 26, 1934, No. 15722. [Class 38 (v)] In a switch of the enclosed type a mechanical indicator having suitable inscriptions to indicate the position of the switch is mounted upon the spindle carrying the coupling contacts and operating handle so as to move simultaneously therewith. As shown in Figs. 3 and 4 the indicator comprises a segment 14 mounted at the end of the shaft 6 carrying the movable contacts 5 and operating handle 10, the segment bearing on its periphery inscriptions to indicate the position of the switch. These inscriptions are visible through a glazed window 19 in the hinged cover of the switch when the latter is in the closed position. The cover is interlocked with the switch handle in the usual manner and a quick-action spring 13 for the movable contacts is provided. The indicator inscriptions may be of any suitable colour or colours and may be of luminous paint.
