Abstract
763,548. Contact members for switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 15, 1954 [Nov. 13, 1953], No. 31555/53. Class 38(5) In a multi-contact electric switch, suitable for the control of a plurality of circuits during one operation, a plurality of bridging contacts 6 are slotted so that they may easily be slipped between fixed bosses 2 and loose insulating washers 3 on an operating bar 1 thus providing that their positions may be changed quickly and without the use of tools to vary the sequence of opening and closing circuits. The contacts 6 bridge pairs of fixed contacts 7, 8, 9 and 10, which are secured by screws (not shown) in the base; each fixed contact having two alternative positions. Helical springs 5 between alternate pairs of washers retain the contacts 6 set against the bosses. The washers which are free to move only in an axial direction carry lugs which engage and locate slots in the bridging contacts. The various methods of dispositioning the fixed and bridging contacts provide a wide range of circuit arrangements one of which is shown in Fig. 5 where, on moving the bar to the left, contacts 10 are disconnected, then contacts 8 are bridges and finally an instant later contacts 7 and 9 are simultaneously bridged.
