Description:

JUC-31F Series Miniature Thermal Switch is a snap-action thermostat with a bi-metal disc as the temeprature sensing element. Its main working principle is to control the temperature by opening or closing the bi-metal strip. It stays at normally closed/normally open status, it opens/closes when temeprature rising and closes/opens when temperature decreasing. It has the characteristics of snap action,high accuracy, long life cycle, high sensitivity, high reliability, small size, light weight, easy installation and so on. We use international TO220/Y220 standard packingJUC-31F Miniature Thermal Switch has been granted national patent, and has passed UL, TUV, CE, CQC, CB and ROHS. It also has passed the 100,000 life test of UL laboratory.
