Abstract

887,369. Regulating switches; switch contacts. SMIT & CO'S. TRANSFORMATORENFABRIEK N.V., WILLEM. April 22, 1959 [May 2, 1958], No. 13764/59. Class 38 (5). Contacts for a rotary selector, e.g. a transformer tap-changer, comprise a bridging contact arrangement consisting of arms 15 mounted in a housing 16, 17 carried by an insulating tube 14 rotatable about the axis of the tube, the housing containing metal screens 19, 20 and fixed contacts 11. The latter are formed on opposite sides of the centre arms of M-shaped members formed from blocks 7 and screen plates 9, 10, the whole of the mountings other than the fixed contacts 11 themselves being embedded in insulation 12. The contacts 11 are arranged at such a distance from the faces of the blocks that when the moving contacts are just touching them, the moving contacts are completely within the space enclosed by the contact blocks. Instead of being radial the fixed contacts 11 may be concentric with the tube 14. The M-shaped member may be replaeed by two U-shaped members.
