Abstract

546,422. Centrifugal switches. HOWARD & BULLOUGH, Ltd., and AIREY, 'E. J. May 19, 1941, No. 6413. [Class 38 (v)] In a centrifugal switch which may be used for disconnecting a transformer from a machine when the machine stops, a contact such as a ball 24 moves outwards by centrifugal force to bring a spindle 15 into electrical connection with a housing 141 which constitutes the hollow boss of a pulley 14 driven by the machine. In modifications, weighted arms-fly outwards to engage the housing 141.
