Rotary Potentiometers, Rheostats are electrical resistors which are used to control the current flow in electrical circuits. They are most commonly used in the control of current in applications such as audio, radio and television equipment, automatic control systems, and other devices. The 91A1A-B28-A20 is an example of a potentiometer or rheostat that can be used in these types of applications.

A 91A1A-B28-A20 is typically constructed with a cylindrical body housing with a sliding control element. On the end of the cylinder is a terminal that rotates to adjust the current flow. Inside the cylindrical body is a resistive element that varies in resistance depending on how far the terminal is rotated. By varying the resistance of the resistive element, the overall resistance of the circuit is changed and the current flow is adjusted. In some applications, the contact terminal of the 91A1A-B28-A20 may be connected to the end of a lever which allows greater mechanical control over the current through the circuit.

The 91A1A-B28-A20 is a variable resistor device and when it is used as a potentiometer it usually has three contacts connected to the resistive element. Two of the contacts are fixed and the third contact is the rotating contact. The fixed contacts are used to provide a reference potential and the rotating contact is used to adjust the potential. As the terminal is rotated the potential at the rotating contact changes in accordance with the resistance of the resistive element.

The 91A1A-B28-A20 can also be used as a rheostat. In this type of application the two fixed contacts are used to provide a reference potential and the rotating contact is used to provide resistance in the circuit. As the terminal is rotated the amount of resistance in the circuit is varied and the current flow is adjusted. This type of rheostat can be used to control current flow in audio, radio and television equipment, automatic control systems, and other devices.

The 91A1A-B28-A20 is an electrical component that can be used for applications requiring the precise control of current flow. It can be used as a potentiometer or a rheostat and can provide a highly accurate means of current control. The 91A1A-B28-A20 is typically constructed with a cylindrical body housing with a sliding control element. On the end of the cylinder is a terminal that rotates to adjust the current flow. It is this element which allows for the precise control of current through the circuit.
