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.

6. Wide application
Installation and Direction for Use:
Method of earth: By means of the metal cup of thermostat connected
in the earthing metal part.
The thermostat should work in environment with humidity not higher
than 90%, free of caustic, flammable gas and conducting dust.
When the thermostat is used to sense the temperature of solid
items, its cover should be clung to the heating part of such items.
Meanwhile, heat-conducting silicon grease, or other heat media of
similar nature, should be applied to the cover’s surface.
If the thermostat is used to sense the temperature of liquids or
steam, it is strongly recommended to adopt a version with
stainless-steeled cup. Moreover, cautious measures should be taken
to prevent liquids getting into/onto the thermostat’s insulation
parts.
The top of the cup must not be pressed to sink, so as to avoid
adverse effect on the thermostat’s temperature sensitivity or its
other functions.
Liquids must be kept out of the thermostat’s inner part! The base
must avid any force that could lead to crack; it should be kept
clear and away from the pollution of electric substance to prevent
insulation weakening that leads to short-circuited damages.
The terminals should be bent, or else, the reliability of electric
connection will be influenced.
