Abstract

719,444. Snap-action switches. NAAMLOOZE VENNOOTSCHAP INDUSTRIELE ONDERNEMING W. H. BRASKAMP. Dec. 19, 1952 [Dec. 22, 1951], No. 32328/52. Class 38(5) A rotary switch comprises a movable contact carrier B urged by a spring 7 towards a fixed contact carrier O, a resilient strip contact 6 on the carrier B bridging diametrically-opposite contacts 5 on the carrier O. Three balls 13 in the carrier B co-operate with a ring of sockets 11 in the carrier O to cause quick switching movement of the carrier B. The carrier B has a recess 15 on its underside with a roof-shaped profile 16 engaged by a driving pin 14 on the operating shaft 3, whereby on rotation of the shaft the carrier B is first lifted away from the carrier O whereupon the carrier B moves ahead of the pin 14 into the next switching position. The shaft is prevented from moving lengthwise by a collar 17 thereon energizing the carrier O. A scale 9 on the shaft 3 observable through a window 10 indicates the switch position.
