Durable and Reliable
With a solid-state design and no moving parts, these switches ensure years of accurate switching with quick response time through whatever situation they face. Our switches have the ability to combine and coordinate two functions in one device and have one or two independently specifiable temperatures, as well as offer reverse polarity protection.

Versatile Performance
- Accurate to ±1.5°F.
- Functions from -20° to 230° F (-29° to 110° C).
- Fully custom set and reset points.
- Operates in a variety of fluids.
- Numerous fittings and connectors available.

Single- or Dual-function Designs
Two outputs from one location assures coordination of functions
through one device. Dual-function maximizes the use of limited
installation ports.

warning/engine shutdown, low transmission temperature
(-10° to 32° F / -23° to 0° C), and fuel temperature.
- Dual-function provides two functions with a single port:
overtemp warning/engine shutdown, fan control/shutter control.
