Abstract

868,978. Mechanical switches without quick action. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1957 [Nov. 30, 1956], No. 36994/57. Class 38 (5). A switch with sliding contacts has rigid contacts 14 arranged on edge in grooves 10 in the surface of a stator plate 2, the contacts having integral stems 15 which pass through holes in the stator and are then twisted or bent to secure the contacts. The moving contacts consist of resilient tongues 29 on plates 26 having arms 28 which lie in grooves 24 on a rotor 19 and are bent to pass through holes 25. The contacts may be arranged for linear instead of angular movement.
