Abstract

753,018. Retractive switches. SPECIALTIES DEVELOPMENT CORPORATION. Jan. 15, 1954 [May 8, 1953], No. 1272/54. Class 38(5) A switch comprises three flexible-conducting strips 10, 11, 12 separated from each other by two series of rubber pads 14, 15, the pads being rhombic-shaped and those of one series being positioned opposite the spaces between those of the other series. A rubber-housing 16 receives the strips the outer two 10, 12 of which are connected together so that in deformation of the housing to engage either of the outer strips with the centre strip 11, an alarm 25 is sounded. Actual dimensions of the switch parts are given in the Specification. Specifications 692,015 and 692,020 are referred to.
