Abstract

710,668. Regulating switches. MALLORY & CO., Inc., P. R. Dec. 20, 1951 [Dec. 27, 1950], No. 29888/51. Class 38(5) [Also in Group XXXVI] A continuously-variable resistance having a contact 33 which moves over a resistance path 12 is converted into one with a step by step action by the co-operation of two projections 92 on an annular spring with a circle of hemispherical studs 70 on the rotor 30. At the switching positions thus determined, contacts such as 98, 99, Fig. 5, may be formed by spraying silver on the carbonaceous resistance material 12. The contact member 33 is shaped as shown in Fig. 4 (part) and has brush contacts 50, 51 engaging the resistance path 12 and wipers 47, 48 engaging a conducting ring 40.
