Abstract

865,888. Air-break switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 1, 1959, No. 29764/59. Class 38 (5). An isolating switch has a resiliently-mounted fixed contact 5 and a movable contact arm comprising three links 1, 2 and 8. The link 1 is pivoted at one end at a pivot 3 on a fixed support and at the other end at a pivot 6 at one end of the link 8. The link 2 is pivoted at one end at a pivot 4 on the support and at the other end at a pivot 7 intermediate the ends of the link 8 which carries a contact member 9. In the closed position shown, the centre of the zone of contact between the fixed and moving contacts 5, 9 lies substantially on a line extending through the pivots 4 and 7 and the pivot 6 lies within a triangle having its corners at the pivots 3 and 7 and the centre of the zone of contact. This disposition of the parts results in the movable contact arm being retained in a stable position with the contact pressure being applied by a spring 11 and/or a spring or springs associated with the pivots.
