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.

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.

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.

Use these controls with motors that run forward and backward, such as motors for conveyor belts.

These dual-control knobs operate independently to control two settings. They have a rubber coating for a comfortable grip. Use them on devices with round shafts to view settings at a glance with a pointer.

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.
