Thumbwheel Potentiometers

Thumbwheel potentiometers are used to control position, speed or voltage in an electrical circuit. The most common type of thumbwheel potentiometer is the 3350 series. The 3350 series features a single-turn rotary switch that is mechanically operated by turning a thumbwheel with one finger. It has a low profile package and is ideal for applications where space is limited.The 3350 series is available in a variety of voltage ratings and resistance values, ranging from 1-503 Ω to 51.53 Ω. It also features a linear taper for the resistance values. The linear taper means that the voltage across the element increases linearly with increased rotational turn. The 3350 series also has an integrated wiper contact to provide a reliable connection between the slider and the body of the potentiometer.The 3350 series has several applications. It can be used in audio equipment, such as amplifiers, as a volume control, in motor speed control, for adjusting voltage levels, and as a digital potentiometer for digital control of an analog signal. The working principle of the 3350 series is simple. When the thumbwheel is turned, the resistance element is rotated, which in turn varies the voltage applied across it. The voltage across the element is then used to control the speed, position or voltage of the device in question. The 3350 series is available in different package sizes depending on the application. They are also customizable with added features such as an adjustable endstop switch and a dust cover. In addition, they are easy to install and highly reliable, which makes them suitable for a wide variety of applications.
