Title: Improvements in or relating to electrical switch mechanism and tripping means therefor
IPC: H01H73/50
Filed: 1949-02-28
Abstract: 661,222. Automatic circuit-breakers. WEST & CO., Ltd., A., and PAVITT, F. . T. Feb. 28, 1950. [Feb. 28, 1949; March 7, 1949] Nos. 5398/49 and 6147/49. Class 38 (v). A switch, which is manually closed and may be either manually or electrically tripped, comprises a lever 9 pivoted at 10 on a plate 8, and a trip plate 5 pivoted at 7 and having a lug 6, the arrangement being such that when the plate 8 is moved to the left, Fig. 3, the end 9a of the lever 9 is restrained by the lug 6, so that its other end 9b engages a projection 3a on a bar 3 carrying contacts 2, which are thus moved against the action of a spring 23 to bridge fixed contacts 1. The plate 8 is latched in this position, Fig. 4, against the action of a spring 36, by the engagement of a lug 8a thereon behind a step 14c on a member 14 pivoted at 15 and biased clockwise by the spring 36. The member 14 is normally held in the Fig. 3, "off", position by lug 8a so that a spring 16 carried by the member 14 holds a plate 13 down upon, so as to immobilise, under-voltage armatures 12, without interfering with the action of overload plungers 11. In the Fig. 4 position, the spring 16 is lifted off plate 13 which is itself lifted off armatures 12 by an arm 14a of member 14. The armatures 12 co-operate with coils 4 and are pivoted on plates 31, their free ends embracing reduced portions of the plungers 11 which underlie lug 6 and two further lugs 34, 35 on trip plate 5. On under-voltage, one (or more) of armatures 12 is released and is pivoted counter-clockwise by a spring 33 to lift the plate 5. The end 9a of lever 9 can now move to the left, Fig. 4, under the bias on bar 3 which bears on the lever 9 at 9b, and. the contacts open leaving the plate 8 latched. The contacts are similarly opened by tilting of plate 5 by one (or more) of plungers 11. To reset the plate 8, member 14 is rotated counter-clockwise to disengage parts 8a, 14c. The switch may also be tripped manually by such rotation of member 14, thereby releasing plate 8 which moves to the right, carrying lever 9 with it, thereby allowing bar 3 to move to the right also. The switch may bemounted in an enclosing casing having push-buttons acting on plate 8 and member 14. Specification  5 49,421 is referred to.
