Compact Threaded Temperature Switches

NPT Male Threaded | NPT Male × NPT Male Threaded |
Since these switches don’t have a housing above the probe, they are often used in tight spaces and low-clearance areas. The threaded probe installs directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature. Use the adjustment screw to set the actuation point. All switches are SPST (single pole, single throw) and control one circuit.
1 Off Switch Starting Position—Switches with 1 Off Switch Starting Position turn the circuit from off to on.
1 On Switch Starting Position—Switches with 1 On Switch Starting Position turn the circuit from on to off.

Install the probe directly into drilled and reamed holes to turn heating equipment on or off at a specified temperature. Use the adjustment screw to set the actuation point. All switches are SPST (single pole, single throw) and control one circuit.
1 Off Switch Starting Position—Switches with 1 Off Switch Starting Position turn the circuit from off to on.
1 On Switch Starting Position—Switches with 1 On Switch Starting Position turn the circuit from on to off.
