Digital Temperature Switch

Designed by Senasys, the Digital Temperature Switch is a cost effective, flexible switching solution that allows for tight differentials and tolerances. The digital switch can be used as a standalone board mounted to the control panel, or as a completed enclosure (as shown).


Designed & manufactured to meet requirements of original equipment manufacturers worldwide.


Senasys products are 100% tested before they leave our facilities.

high accuracy

Wide temperature switching and differential range with tight tolerances.


Senasys products are designed and manufactured in Eau Claire, Wisconsin, U.S.A.

The digital temperature switch is a simple solution to monitor and control temperature in heating and cooling applications. Built for original equipment manufactures, the digital temperature switch can be used a standalone sensor inside an enclosure, or mount the board directly to your control panel. Using a 10 Amp, SPDT relay, the digital temperature switch can control various equipment such as a fan or compressor. Using a digital thermometer, the digital switch is highly accurate with tight tolerances and differentials.

Our digital temperature switch is available with multiple different sensor options using a standard RTD sensor including:

  • Probe Style
  • Epoxy Sealed Surface Mount
  • K-Type Thermocouple
