Six-foot potentiometer B50K, pins are generally one or three terminal for the total resistance value; the middle terminal changes, according to the need to connect, take a meter; two rows up and down, you can use only one row.

Potentiometer is a resistor element with three lead-out terminals and resistance value can be adjusted according to a certain law of change. Potentiometers are usually composed of resistors and movable brushes. When the brush moves along the resistor, the resistance or voltage which is related to the displacement is obtained at the output end.

The potentiometer can be used as either a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor, because its function in the circuit is to obtain the output voltage which is related to the input voltage (the applied voltage), so it is called potentiometer.

The real difference between a dual gang potentiometer with switch and a single potentiometer:

Single potentiometer is one of the potentiometers used more often. Its axis only controls one set of potentiometers. The double potentiometer is that two potentiometers are mounted on the same axis. When the rotation axis is adjusted, the contacts of the two potentiometers rotate at the same time. For example, in stereo equipment, when the volume and tone of two channels need to be synchronized, the double potentiometer should be selected. For example, WH134-K2 is a dual gang potentiometer with switch.Some dual potentiometers are asynchronous asynchronous axes, that is, the two axes are concentric axes, which do not interfere with each other, and each axis adjusts its associated contacts. For example, the WH134-3 type is a dual off-axis non-switching potentiometer.
