Description:
KSD301 series Snap Disc Thermal Switch is a snap-action thermostat with a bi-metal disc as the
temeprature sensing element. It can be reseted automatically. 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.It is
widely used in rice cooker, microwave oven, electric water
boiler,room heater, egg boiler and electric steamer,etc.
