Trimmer potentiometers like ST2A104 consist of three main parts - a one or two section rotor, a fixed contact plate and a moving contact plate. The fixed and moving contact plates have a series of metal plates arranged in a specific pattern which provide resistance to the current. This arrangement controls the current in the circuit, thus providing a very precise adjustment to the resistance. The ST2A104 has four terminals - two terminals for DC power, one for an AC voltage and one for a variable control voltage.

ST2A104 trimmer potentiometers are used in a wide variety of electronic circuits to provide precision control over a varying current. They are most commonly used in audio equipment as a means of controlling the balance between the left and right channels. They are also used as adjustable voltage regulators in battery powered systems, providing a constant voltage under varying loads. Their primary application in the home is in providing precise control of the audio output level of a stereo amplifier.

The working principle of the ST2A104 is based on the principle of potentiometry. The design of the device involves the use of a resistive element that is connected to a control voltage. A variable current is applied to the element, which changes its resistance accordingly. When the correct resistance is obtained, the control voltage is held constant, and the current can then be adjusted to provide the desired level of output.

The ST2A104 trimmer potentiometer is a precision device that is typically used in audio equipment, battery powered systems, and other sensitive electronic circuits. The device provides very precise adjustment of resistance and current, allowing for precise control of the output to the system. The sliding arm and contact plates of the device provide a wide range of adjustment, allowing for a wide range of output levels. The device is very reliable and will maintain its settings for long periods of time, even in harsh environments.
