Abstract
851,729. Air-break switches; contact members for switches. TRANSFORMATORENWERK K. LIEBKNECHT VEB. June 26, 1957, No. 20234/57. Class 38 (5]. In a contact set particularly for outdoor switches subject to icing-up, a movable blade slides between sets of pivoted contact pairs which are linked together for movement between stops so as to assist in the breaking of any ice on the contacts. The contact pairs 2 and 3 are each pivoted, at 6, 7, on a part spherical bearing 17 urged against a contact carrier 18 by a spring 13. Springs 9 . . . 12 urge the elements of the pairs toward each other and are guided on rods 20 carrying a link 8 which connects the contact pairs. When the blade 1 is moved to open the contacts, both contact pairs move about their pivots until a stop (not shown) is engaged in the Fig. 5 position, there being relative motion a between their ends. Three contact pairs may be provided (Figs. 6 and 7, not shown) with one link connecting them together.
