Abstract
1,259,019. Contact-members for switches. ALLMANNA SVENSKA ELEKTRISKA A.B. 14 May, 1969 [15 May, 1968], No. 24573/69. Heading H1N. The spring-pressed contact fingers 3 of a heavy current switch have arc-resistant tips 8, e.g. of copper-tungsten, each tip 8 having an anchoring fin 10 guided in a longitudinal groove 14 in the finger 3 with a rearward projection 11 having hooking engagement in the groove 14 and with a forward projection 12 abutting a supporting edge 15 or 22 on the contact holder 4, 20. Edge 15 is on an arcing ring 5 of coppertungsten. The contact surface 9 of tip 8 is in a recess 13 of the finger 3. A plurality of fingers 3 in a holder 4 provide a sheath contact 1 for a movable plug contact 2. A clip-type contact member 16, Fig. 5 (not shown), has two such fingers 3 engageable by a knife contact member 17. An abutting contact 21 engages a plurality of fingers 3 arranged in a circle in a stationary contact holder 20, a plurality of rubber washers 23 and a curved plate 24 providing damping for each finger 3.
