Abstract

175,969. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Aalborg, C.). Feb. 26, 1921, [Convention date]. High-potential switches; partly electromagnetic.-In a switch having a flexible contact cooperating with a butt contact, the flexible contact comprises a pair of flexible members, e.g. laminated handles 12, 13, permanently disposed at an angle with respect to the normal to the contact surface and outwardly with respect to one another so that the magnetic effect of the current tends to free them on to the butt surface 6. As illustrated in Fig. 1, which is an end elevation of a double-break switch using laminated contacts 12, 13, the laminations are attached to the bridge-piece 5 so that they lie in planes parallel to the direction of movement of the bridge-piece and their splayed ends are at right-angles to the usual direction of laminations in contacts of this type. Movable and stationary arcing tips 17, 10 are provided. Specification 170,556 is referred to.
