Abstract
1,077,527. Variable resistors STACKPOLE CARBON CO. March 25, 1965 [Oct. 2, 1964], No. 12652/65. Heading H1S. [Also in Division H2] The combined variable resistor and push pull switch of Specification, 886,293 is modified by the addition, in series with the switch, contacts (11, 12, 15) of an overload responsive bimetal switch (26, 28), the bimetal (28) being bent to hook over the extra feed contact (26) formed by a terminal (31). The bimetal. (20) is straightened on overload and released from fixed contact (26); it is reset by a spring member (32) acted on. by a conical extension, (38) of the switch actuating shaft (4) when the later is moved to open the switch.
