Abstract
474,220. Centrifugal switches. MASCHINENFABRIK OERLIKON. May 25, 1937, No. 14508. Convention date, June 23, 1936. [Class 38 (v)] A centrifugal switch, particularly for shortcircuiting starting resistances of an electric motor, comprises a contact carrying lever 1 pivoted between a knife edge bearing 4 and a similar bearing 7 on a compression spring 6 supported on a bearing 9 adjustable from the exterior of the casing. The lever 1 is of trough section and carries a contact ball 2 for engagement with a pair of fixed contacts in the speeded up condition illustrated, in which the spring 6 has almost reached its deadcentre position and so exerts little force.
