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.
