Abstract

1312400 Retractive switches VEREINIGTE BAUBESCHLAGFABRIKEN GRETSCH & CO GmbH 22 Nov 1971 [12 Jun 1971] 54051/71 Heading H1N A mat type pressure switch comprises two contact sheets 1, 2 of conductive resilient layer plastics material or natural rubber (graphite added for conduction properties) separated by a layer 3 comprising a grid mat 4 of a foamed resilient material. The mat may be made self-adhesive on its outer sides. A synthetic plastics material or natural rubber in the form of a bag or layers is used to envelope the unit in a water tight manner. Connection elements 6 with connection leads 7 are mounted on sheets 1 and 2.
