Abstract
814,528. Regulating switches; switch contacts. CLAVEL, J. Aug. 31, 1955 [Aug. 31, 1954; Dec. 21, 1954], No. 24984/55: Class 38(5). In a switch in which the fixed contacts 1b are arranged in an arcuate row and selectively connectible to a continuous contact 1a, a pair of contacts 3 co-operating with the contacts la, 1b have cylindrical cavities 9 in which are located balls 8 of a slightly smaller diameter carried by bolts 10 riveted to spring blades 4. The ends of the latter are interconnected by members 30 which pass freely through sleeves 31 fixed to a support 6 carried by a rotatable driveshaft 7. The contacts are electrically interconnected by a flexible lead 12 connected to clips 11 on the contacts 3. Instead of circular contacts, contacts 1b of the shape shown in Fig. 5 may be employed. In another arrangement (Fig. 1, not shown), the continuous contact and the fixed contacts are in the same plane, being engaged by studs carried by opposite ends of the support 6. The spring blades 4 are carried by rigid strips attached to the ends of the support.
