Danfoss Temperature Switches

Technology
Danfoss thermostat products are electromechanical controls which provide a volt free switch contact which will operate at the set temperature, thus providing a simple ON /OFF control. The products provide user adjustment to increase or decrease the differential temperature between switch ON/OFF on rising / falling temperature, this enables their operation to be tuned to the application. Danfoss utilise over 60 years experience in design and manufacture of temperature switch products making them the best in their class.

Danfoss temperature switches are well established, and designed and manufactured in their ultra-modern factory, using state-of the-art production equipment.
