A rotary potentiometer, or pot, is a three-terminal resistor with a circular wiper that slides along a resistive element to provide a variable voltage divider. They are used to measure angular or linear position, and to change or control electrical characteristics in a circuit. The 3549S-1AE-103A is a rotary potentiometer designed to measure angular displacement, and it comes with a built-in rotary switch. It is widely used in automotive, medical, and industrial applications.

A potentiometer is composed of a resistive element made of conductive material such as carbon, graphite, or metal foil, and a wiper that slides along the resistive element. The resistive element is connected to two terminals, and the wiper is connected to a third terminal. The position of the wiper determines the operation of the potentiometer, and it can be adjusted by rotating the shaft of the potentiometer. The 3549S-1AE-103A has a rotary switch that is activated when the shaft is rotated, which is useful for controlling the operation of other devices in the same circuit.

The working principle of a rotary potentiometer is simple. When the shaft is rotated, the wiper moves along the resistive element, which changes the resistance between the two terminals. The resistance between the two terminals is proportional to the angular displacement of the wiper, and the voltage across the terminals is proportional to the resistance. The voltage can be used to measure an angular displacement, or it can be used to adjust the characteristics of a circuit, such as gain or resistance.

The 3549S-1AE-103A has a slide switch that is activated when the shaft is rotated to a certain position. This allows the potentiometer to be used for device control in a circuit. The switch can be used to control the power supply to an electronic device or to activate a device when the shaft is rotated to a predefined position. The potentiometer also has a built-in noise suppresor that helps reduce the amount of electrical noise in a circuit.

The 3549S-1AE-103A is a popular choice for automotive, medical, and industrial applications because it is easy to use, durable, and reliable. It can be used to measure the displacement of a device and to adjust the characteristics of a circuit. It is also used to control the power supply to an electronic device or to activate a device when the shaft is rotated to a predefined position. This makes the 3549S-1AE-103A an ideal choice for a wide range of applications.
