Abstract

1,107,642. Press-button retractive switches. BURGESS PRODUCTS CO. Ltd. 14 April, 1965 [15 Jan., 1964], No. 1789/64. Heading H1N. A number of switches are mounted on a common support 1. Each switch comprises a transparent or translucent push-button 17 bearing against a slider (12), Figs. 2, 3, having a projection 14 on its end which, when the button is depressed, bears against the plunger 15 of a micro-switch 9 mounted, by means of insulating plates 10 and spacers 11, between plates 7 which are extensions of the members (4), Figs. 2, 3, retaining the sliders and pushbuttons on support 1. A retracting spring 20 is provided. A projection 23 on each slider projects through an opening 22 on support 1 and when a button is depressed the V-shaped end of the projection 23 on the associated slider engages the oblique faces 29 on blocks 25 which slide to prevent any other button from being simultaneously depressed. A light bulb (19), Fig. 2, may be provided to illuminate each push-button. Additional micro-switches may be provided in place of spacers 11. The assembly may be mounted on a panel with buttons 17 projecting through openings which may be waterproofed by a grommet or seal or bellows.
