Harsh Environment Potentiometers


Rated NEMA 4X and 13, these potentiometers are protected from debris, washdowns, and oil/coolant spraying. Also known as variable output switches or rheostats, they vary electrical flow to control speed, volume, and light intensity.

Potentiometers





Vary electrical flow to control speed, volume, and light intensity. The number of turns affects the resolution—the higher the number, the better the control. Also known as variable output switches or rheostats. A knob is required (not included).
Switches with ball bearings have a smoother rotation and a longer service life than other potentiometers.

Digital Potentiometers
More precise than analog potentiometers, these have a three-digit display that is easy to read. Also known as variable output switches or rheostats, they vary electrical flow to control speed, volume, and light intensity.
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.

Flow Switches with Indicator for Water

For flow monitoring at a glance, these switches have a plastic window with a rotor indicator that spins when flow is present. They activate or deactivate equipment when the flow rate reaches your set point. All have an adjustment screw for altering the set point to suit your application. Switches are single pole, double throw (SPDT) and can be installed to turn one circuit from "off" to "on" (normally open) or from "on" to "off" (normally closed).
Switches with a polypropylene body are lighter than sights with a metal body.
Switches with a 316 stainless steel body are more corrosion resistant than switches with a brass body.
