Abstract

832,393. Electromagnetic switches. LUCAS (INDUSTRIES) Ltd., J. June 13, 1958 [June 26, 1957], No. 20107/57. Class 38 (5). An electromagnetic switch which may be used in a dynamo current or voltage regulator, has its armature d biased away from a core b and coil c by a blade spring g which may be an extesnion of the armature mounting spring f. The free end of the spring g engages a cam surface n on a plate k pivoted on a pin m. The bias of the spring is varied by rotation of the plate k by means of a special tool (not shown) which engages in a hole p and with teeth o on the edge of the plate k. A clamping screw q is provided.
