Electronic Temperature Switch

Designed by Senasys, the Electronic Temperature control switch allows for fast, easy set points, limits and differentials. Use it stand alone or design it into your next machine. Our 3 base models are listed, but many other options are available.

If you do not know your systems switching temperature purchase an electronic temperature control switch for precise measurements with tight tolerances and differentials.

simple solution

The digital temperature switch is a simple solution to monitor and control temperature in heating and cooling applications.

High quality

We take pride in quality control & reliable operation of our components. Every switch is individually tested before it leaves the plant. Every switch is individually 100% tested before it leaves the plant.

custom options

Other custom options such as, amperages, lead lengths, case and display configurations, sensor and thermowells are available.


Products are designed, manufactured, tested and shipped from Senasys’ facilities in Eau Claire, WI to clients across the globe. 

Designed by Senasys, the D Series electronic temperature switch is a cost effective, flexible switching solution that allows for tight differentials and tolerances. The switch can be used as a standalone board mounted to the control panel, or as a completed enclosure.

Our electronic temperature switch is a temperature sensing device which uses an RTD sensor inside an epoxy filled cap, or probe style.  The switch changes states at a fixed temperature, or can be adjusted from -50°F to 200°F.
