Abstract

764,534. Centrifugal switches. ENGLISH ELECTRIC. CO., Ltd. April 7, 1955 [Jan- 15, 1954], No. 1244/54. Class 38(5) A speed responsive, switch actuating mechanism comprises a carrier member 10 mounted on a rotatable shaft, a switch actuating member 13 slidably mounted by means of lugs 14 on the carrier member, a plurality of coil springs 15 attached to and connecting the actuating member to the carrier member, and centrifugal weights 22 freely supported by the coil springs. The springs are disposed with their axes tangential to the shaft and each is formed with coil portions 16 spaced apart by an offset part 17 and two legs 18. The legs 18 engage lugs on the carrier member and the part 17 engages lugs on the actuating member. Weights 22 are disposed between the coil portions by means of screws 23. When the speed increases the weights move outwards causing the actuating member to move to the left (Fig. 2), thereby allowing the contact 26 which is biased to the left to disengage contact 27.
