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

Create a seal around a potentiometer shaft to keep out moisture and dust.

Often used in large, open workspaces, these switches can be wired on opposite ends of the room to control the brightness of lights on the same circuit. They're also known as three-way switches.

For monitoring the number of shaft turns on instrumentation, these knobs have easy-to-read scales or digits for quick and accurate readings. Use them on devices with round shafts.

Quickly identify equipment controls and components by their color. Use these knobs to control devices with round shafts and view settings at a glance with a pointer.
