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. JUC-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. It is widely used in printed circuit board equipment, power supply equipment, audio amplifier, welding equipment, automation equipment and instrumentation for temperature control and temperature protection.
Applications:
● Printed circuit board equipment
● Power supply equipment
● Audio amplifier
● Welding equipment
● Automation equipment
● Instrument and apparatus
