Control a device with 10 times the precision as our standard potentiometers.

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.

Detect motion near your light fixture to turn lights on and off. Compared to switch-mount motion controls that detect from a single wall, these controls have a better view of the entire space since they sense motion from above.

Fine-tune motion-sensing light controls from your smartphone or tablet. Mounting on the ceiling gives these light controls a clearer view of the room than wall-mount sensors, so they switch reliably.

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

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.

To build a custom precise-control knob or thumb screw, pair one of these knobs with a socket head screw. Turn the knob to move the screw 0.005" per graduation and make precise adjustments.
