Abstract

827,168. Snap-action switches; retractive switches. BEER, D. C. March 1, 1956, No. 34844/54. Class 38 (5). A switch has a rocking contact lever 67 pivoting on either points 70 or 71 of a support 64 depending upon the direction of movement of a dolly 72. The latter has a semicircular port 73 co-operating with a recess 74 in a base 58 and in side plates 84, the movement being limited by faces 86, 87 on the plates 84. The dolly carries a spring-pressed plunger 80 which bears on the rocker and has an enlargement 72b which supports plates 76, 77, plate 76 having a slot 78 and plate 77 an aperture 79 receiving the part 72a of the dolly. The base 58 has a shoulder 83 about which the levers 76, 77 pivot when the dolly is moved counterclockwise and the spring 81 of the plunger 80 provides a restoring torque on these levers and on the dolly when so moved, so that the dolly and contacts are restored by the spring when released. The base may have a second shoulder 83 so that the switch is retractive in both directions, or may have a recess 82, as shown, so that the switch is stable when the dolly is moved clockwise. The switch has a snap-action in each direction.
