Fixed-Setpoint Threaded Temperature Switches
Set to actuate at a specific temperature, these switches are easy to setup and prevent changes to the setpoint. They have a threaded probe, so they install directly into tanks, pipelines, and other process components to turn equipment on and off at a set temperature.
Narrow differential switches reset after a small temperature change in the opposite direction of your switch's actuation. For example, in a rising-actuation switch, they reset after the temperature falls 3° below the setpoint. Use them in systems where temperature changes slowly and where you need precision.
Rising actuation switches activate when the temperature rises to the setpoint and then reset when the temperature falls below the setpoint. Choose rising actuation SPST-NO switches to power a cooler or trigger an alarm. Choose rising actuation SPST-NC switches to turn off a heater or other equipment when the temperature rises to the setpoint.
Falling actuation switches activate when the temperature falls to the setpoint and then reset when the temperature rises above the setpoint. Choose falling actuation SPST-NO switches to power a heater or activate an alarm. Choose falling actuation SPST-NC switches to turn off a cooler or other equipment when the temperature falls to the setpoint.
All switches are NEMA 4 and 13 rated to seal out dirt, oil, and water from washdowns. UL and C-UL listed switches meet U.S. and Canadian safety standards.
