Abstract
Abstract A variable resistor with switching means for use in remote control system comprises a variable resistor and a switching means, said switching means being interlocked to said variable resistor such that said switching means is operated only when it is desired to adjust the variable resistor. With this variable resistor with switching means the operation of the switching means and adjustment of the variable resistor for volume control or the like can be effected through a single operation.
