Precision Potentiometer Dealers

ETCC is one of the leading precision wire wound potentiometer manufacturers. Potentiometers are a three terminal resistor with a sliding contact that forms an adjustable voltage divider. Potentiometer is commonly used in as a device to control volume in audio appliances as sudden high volume can really damage our ear drums and in some extreme cases a person might lose the ability to hear properly. Thus, this is an important part of manufacturing. These are used to directly control significant power as the power degenerated would be comparable to the power in the controlled load.
