Abstract

1318409 Retractive switches LEMATEX Inc 15 Sept 1970 [25 Sept 1969] 44003/70 Heading H1N A laminar multiple switch assembly comprises a non-conductive base panel 20, frame-like spacer means 23 disposed thereon to divide it into a plurality of switching areas 22, a fixed contact 21 in each area 22, a deformable panel 26 selectively depressible into each area 22 and a flexible conductive laminate 28 formed by a stamping of substantially flat resilient conductive material formed with frame-like portions conforming to and supported on said spacer means and an integral movable switch element resiliently suspended from said frame-like portions in each of said switching areas for move. ment towards said base panel 20 to engage the corresponding fixed contact 21 on depression of said deformable panel 26 in the respective area 22. There may be a plurality of fixed contacts studs in each switching area (Figs. 5 to 9, not shown) or the fixed contacts may comprise printed circuitry on the base panel 20. The moving contacts are preferably suspended on spirally oriented arms stamped out of beryllium copper laminate 28 (Figs. 10 to 15, not shown) with contact fingers (39, 39<SP>1</SP>) providing a wiping action on the fixed contacts. The perimeter of the assembly may be hermetically sealed and a suitable gas filling provided.
