Indicating Knobs
Control devices with round or D-shaped shafts and view settings at a glance with a pointer.
Knobs for D-profile shafts simply press on and stay in place.
Knobs for round shafts include a set screw to secure them in place.
Plastic knobs are a lightweight alternative to metal. They resist oil, grease, and solvents. Phenolic has good scratch resistance. ABS has excellent impact resistance.
Aluminum knobs have mild corrosion resistance, are lightweight, and are nonmagnetic.

Digital Potentiometers
More precise than analog potentiometers, these have a three-digit display that is easy to read. Also known as variable output switches, they vary electrical flow to control speed, volume, and light intensity.
Ceiling Fan Speed Controls
Convert one or more single-speed ceiling fans to variable speed.
Controls with a switch can be turned on and off without adjusting the speed, reducing wear on the motor. Unlike knob-only controls, you can use use the switch to quickly start and stop fans without changing your settings.
Controls with a knob/switch have a rugged, sealed case that stands up to damp, rough, and other demanding environments.
Connect knob-only and slide bar/switch controls in a single-gang switch box.
