Abstract

1,017,426. Switch contacts. W. GRUNDER. April 1, 1963 [May 24, 1962], No. 12793/63. Heading H2B. Springs 1, Fig. 1 (not shown), of a contact assembly are held in place, despite shrinkage due to ageing of intermediate layers 3 of hard paper or insulating fibre, by synthetic resin, e.g. polystyrene, injected into aligned apertures 9 in the springs 1, supports 2 and layers 3 to form one or more pins. A yoke 8 of a relay may also have apertures aligned with the apertures 9 so that the assembly is attached to the yoke by the synthetic resin pins or it may be additionally attached by a screw 7 passing through a hollow rivet 5 holding the assembly together. The rivet 5 is fitted into the assembly to provide initial compression before the resin is injected into the apertures.
