Mechanical Temperature Switch NC20 adopts the principle of bimetallic sheet. Whenthe temperature reaches the set value, a section of bimetallic sheet which is made into a curved ring is heated to expand and trigger the built-in device. The switch action.

The contact part of Mechanical Temperature Switch NC20 with the medium is made of brass. The interface thread is available in G1/4,G3/8 and M22×1.5. The temperature range is 30°C... 120 °C.
Principles Characteristics
Mechanical Temperature Switch NC20 series temperature switch can meet the different requirements of temperature control in hydraulic, lubrication
and transmission series. It is used to detect whether the temperature exceeds the maximum or minimum limit.
