Abstract
847,648. Press-button retractive switches; indicators for switches. DOGGART, J., and FRIEDLAND Ltd., V. & E. May 27, 1957 [March 19, 1956], No. 8559/56. Class 38 (5). A switch, e.g. a bell push, comprises an opaque push button 11 secured to an eyelet 22a slidable in a transverse part 14 of a sleeve member 13 made of light-conducting material, e.g. methyl methacrylate. The eyelet 22a carries a contact plate 32 which can be pushed against the action of a spring 24 to bridge two fixed contacts 27 held in the part 14. A recess in the member 13 is lined with a red light-conducting piece 15 and contains a lamp 35 connected across terminal screw 39, threaded into the contacts 27. When the switch is open, the lamp is lit and the button 11 is thus surrounded by an illuminated ring enabling the switch to be found in the dark. A dolly may be used in place of the push button. A spider 43 with spring arms 42 is attached to the switch and the arms are adapted to engage in an opening in a mounting member (Fig. 4, not shown).
