Abstract

566,807. Thermal switches. MIDLAND ELECTRIC MANUFACTURING CO., Ltd., and VICARY, A. W. July 6, 1943, No. 10970. [Class 38 (v)] In a thermal overload switch, wherein a bimetallic or other thermal member b moves a contact lever c into engage. ment with an adjustable contact to control an electromagnet a, a rotatable cam varies the position of a slide carrying the adjust- . able contact. In the form shown, the adjustable contact h is mounted on a slide, a pin n on which co-operates with a spiral groove m on the rotatable cam k which is fitted with a dial p co-operating with a fixed pointer.
