Abstract
102,523. Testor, J. F., and Testors Fabriks-Aktiebolaget, F. Jan. 20, 1916. Switches, quick-break; contacts; sparking, preventing.-A knife switch, having one or two contact-arms 9, 10 moved to open and closed position by press-buttons acting on the opposite ends of the arms, has the fixed contacts 16 let into the base 1 so that the side faces 15 on a projection 6 on the base form continuations of the contact surfaces. The arms 9, 10 carry pieces of insulation at the contact ends to prevent sparking; or the insulation may be fixed to the base, and the arms enter between the insulation and the contacts 16 when the switch is closed. The arms have projections 21 formed in their length, the projections entering recesses in the metal support 2 when the switch is opened and causing a quick break, the springs 12, 13 assisting the opening movement. When the switch is closed, the projections 21 bearing on the side of the support 2 co-act with the springs to ensure good contact. The switch may be used for one or two circuits.
