ABSTRACT:
An electrical switch contact arrangement having a spring which snaps the movable arcing contact away from the stationary arcing contact at a high rate of speed to open the arcing contacts, but only after the movable main contact has moved through a considerable portion, for example, at least about 50%, of its opening movement away from the stationary main contact. The spring is tensioned as the main contacts open. At an intermediate point during the opening movement of the movable main contact, the moveable main contact positively initiates opening movement of the arcing contacts whereupon the spring snaps the arcing contacts open at a high rate of speed independent of the opening speed of the main contacts.
