Abstract

583,776. Press-button switches ; indicators; switch cases. EXPRESS LIFT CO., Ltd., and KRUGER, S. Dec. 4, 1944, No. 24168. [Class 38 (v)] The button of a press-button switch, or an indicator associated therewith, or both, can be illuminated by a lamp in a lateral housing on the body 1. The latter has a forked extension 1<1> between the limbs of which is secured, by a U-shaped spring clip 3, a slidable base 2 carrying brackets 4 carrying fixed contacts 6. An opaque indicator label 10 is located between a transparent push-button 7, in the shape of an ellipse in plan, and a spring plunger 1' on a reciprocable stem 12. The slidable movable contact 14 is urged by a spring 16 against a slidable dolly 13 urged upwards by a spring 15, whereby both parts 13, 14 move independently of the stem 12 to allow contact-alignment and button-overtravel. The body 1, 1<1> is assembled on a panel (shown dotted) by a U-shaped member 19 which supports a spring 18 and is received in a groove 20 in the body. The lamp 20' is carried by a holder 22 which is slidable in a lateral housing 21 with a spring fit and has a longitudinal extension 25 with a loop 26 whereby it is mounted on an extension 24 of the U-shaped member 19. The switch may be normally closed, Fig. 7 (not shown), and may have housings on opposite sides for different coloured lamps.
