Rotary Switches
Control multiple devices with one switch. Turn the shaft to change switch positions. Each position closes a set of contacts per circuit, so you can select between multiple devices on one or more circuits.
Switches for 13/32" panel cutout diameter require a knob.

Harsh Environment Potentiometers
Rated NEMA 13, these potentiometers protect against debris and splashing oil and coolant. Also known as variable output switches, they vary electrical flow to control speed, volume, and light intensity.
NEMA 4X rated potentiometers withstand weather, washdowns, and corrosion.
