Abstract

623,338. Regulating switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 1, 1947, No. 11691. Convention date, May 1, 1946. [Class 38(v)] In a switch for changing transformer connections, the fixed contacts 8-10 are mounted on the ends of insulating tubes 19 arranged in holes 18 in insulating supports 3-6 and having slots 20 which co-operate with recesses 21 in sleeves 22 surrounding the tubes 3-6, so as to hold the parts together. The co-operating moving contacts 11, 12, 13 are fixed on insulating segments 14-16 mounted on a shaft 7, comprising two tubes 23 having projections 24 and indentations 25 which engage in grooves 26 in bosses in the segments 14-16. The switch may be used for series-paralling the transformer windings, Fig 4, (not shown), or reversing their phases, Fig. 5, (not shown).
