Abstract

744.501. Indicators for switches. DIAMOND H SWITCHES, Ltd. June 23. 1954 [July 1, 1953], No. 18284/53. Class 38(5) A neon lamp 10 serving to indicate the condition of a thermostat 3 is mounted on a member 9 attached to a facia plate 1. the latter being removably attached to a panel 2 by spring arms 27 of a plate 26 which co-operate with recesses 28 in the plate 1, the plate 26 being secured by the nut 25 which mounts the thermostat on the panel 2. A rearwardly extending casing part 13 of the member 9 contains a resistance connected in series with the lamp 10 and has a pair of contact plugs 15 serving as the lamp terminals, the plugs engaging socket contacts 17 in a casing 18 carried by the thermostat when the plate 1 is held by the arms 27. Thus the plate 1 and its attached lamp 10 may be readily removed after first disconnecting the control knob 6 from the thermostat spindle 4. The lamp has a translucent cover 21.
