Compact Threaded Temperature Switches
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 single pole, single throw (SPST) and control one circuit.
Normally open switches turn the circuit from off to on.
Normally closed switches turn the circuit from on to off.

Insertion Temperature Switches
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 single pole, single throw (SPST) and control one circuit.
Normally open switches turn the circuit from off to on.
Normally closed switches turn the circuit from on to off.
