D540/7T,D540/7TK Temperature controllerDetailed product description：

D540/7T, D540/7TK temperature controller

Process of action of single pole double throw micro switch:
Connect terminals 1-3 when the temperature rises to the upper switching value
Disconnect when the temperature of terminal 1-2 rises to the switching value
The controller adopts a temperature sensitive sensor. Can be used for neutral media. The set value of the controller can be adjusted within a range of -20 to+70 ℃.
