This is a listing of Variable Resistor Manufacturers.
The types of products or devices the manufacturers produce are listed under the company name, in alphabetic order.
Manufacturers with carbon or cermet under their listing is just a notation for the material used.

POTentiometer Information{Resistor Shunt Design example}, {This Web Site}
Resistors Manufacturers {This Site}
There are three types of Variable Resistors, each of which consist of a three terminal resistor; two fixed end leads and one lead attached to a variable tap. The variable tap is movable to change the resistance, between the tap and terminal.
Potentiometer: Designed for frequent changes ~ a volume control
Trimmer: Designed for less then frequent changes [occasional]~ a trim pot on a PCB to finalize a circuit resistance.
Rheostat: A three terminal potentiometer which only uses two terminals.
The material used determines the Variable Resistor's operational range [temperature and wattage]. The material may be;
Carbon composition, Resistive wire [Wirewound], Conductive Plastic, and Cermet [a mixture of ceramic and metal].
