Abstract

923,891. Laminates. C. A. KING. June 7, 1960 [June 6, 1959], No. 19424/59. Class 140. [Also in Group XXXVII] A mat constituting an electric switch closed by the application of pressure comprises a sheet of foam or sponge rubber 10 having apertures 11, or composed of cross-laid spaced strips, secured on each side by adhesive to metal foils 12 which close the switch on contact. Outer layers 13 of rubber provide a sheath, the edges of which may extend beyond the sheet 10 and be sealed together. The mat may be enclosed in outer layers of waterproof iron-conducting material.
