Abstract

694,703. Interrupters. BRITISH TABULATING MACHINE CO., Ltd., and RIGBY, I. V. Nov. 26, 1951, No. 27677/51. Class 38 (v) A switch suitable for high-speed operation comprises a pair of contact blades 3, 4 fixed to a bracket 2, the blade 3 being actuated by a pin 22 on an arm mounted on an eccentric 17, and the blade 4 having a rigid member 7 for limiting its movement in one direction, and a resilient, e.g. rubber, backing strip 10 for restraining movement in the other direction. The free end of strip 10 is clamped to members 11 which are adjustable by screws 14 so as to set the tension of the strip 10.
