Abstract

1,077,677. Variable resistors. P. R. MALLORY & CO. Inc. Oct. 12, 1964 [Oct. 23, 1963], No. 41521/64. Heading H1S. [Also in Division H2] A switch combined with a thermal cut-out (see Division H2) may be mounted with a rotary variable resistor (Fig. 6, not shown), for operation by axial movement of the resistor shaft.
