Abstract
474,218. Centrifugal switches. MASCHINENFABRIK OERLIKON. May 19, 1937, No. 13942. Convention date, June 18, 1936. [Class 38 (v)] A centrifugal switch for cutting out the starting resistances of an electric motor comprises a contact ball 1 loosely mounted in a housing 2 which on the motor speeding up, moves upwards due to centrifugal force allowing the ball 1 to bridge contacts 4, 5, 6. The housing 2 has projections 7 which engage lugs 8 on the casing to limit the outward movement of the housing so that the ball 1 is entirely free to bed down on the contacts, and contact pressure is entirely due to the centrifugal force of the ball itself.
