Abstract

829,965. Retractive switches; switch contacts. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 25, 1958 [Aug. 8, 1957], No. 24976/57. Class 38 (5). A switch comprises a helical spring 6 whose ends are slipped over and soldered to brackets 11, 12, of terminals 4, 5, such that several coils of the spring will contact a metal plate 2 on application of pressure by a plunger or a finger operating through a dust-proof rubber cover. In a changeover switch (Fig. 3), a spring 13 normally engaging a contact strip 16, engages a contact 20 on depression of a plunger 18. The contact plate 2 may be formed by a " printed circuit " process and the metal parts of the switch are plated with a precious metal.
