Resistors

Limit the electrical current that flows through your circuit, adjust signal levels, and divide voltages.

Potentiometers

Potentiometers

Vary electrical flow to control speed, volume, and light intensity. Also known as variable output switches or rheostats.

Digital Potentiometers

Digital Potentiometers

More precise than analog potentiometers, these have a three-digit display that is easy to read.

Harsh Environment Potentiometers

testString

Rated NEMA 13, these potentiometers protect against debris and splashing oil and coolant.

Variable-Speed Foot Switches

Variable-Speed Foot Switches

When the pedal is pressed, the built-in potentiometer adjusts the resistance to vary the speed for motor drives.
