, (7', 8') contact spacing is resistive element layer 2,
(2') Resistance layer 3. (3') is set at a slightly larger angle, so when slider e (6') is exactly in the middle of the rotation angle (the position indicated by the dotted line in Figure 5)
, the terminals t, n, and m are connected with a good conductor and are in a short-circuited state. Therefore, at this time, the variable resistor does not work in the circuit shown in FIG. 5, and the output voltage V of the amplifier is directly applied to the speakers A and H, so that they work at full power.

This is an attempt to solve the above problem by increasing the area of the resistance layer formed on the same substrate. By forming the resistive layer separately, the area of the resistive layer can be increased, so the power that the resistive layer can withstand can be increased. Because there is almost no heat generation in the parts, there is no need to use high heat-resistant materials for the conductor layer substrate, and one conductive layer substrate is used for the resistance layer substrates before and after the double variable resistor. It is also possible to share the front and back sides of the board.
