Snap Action Temperature Switch KSD301
The snap action temperautre switch KSD301 is a temperature control switch that uses bimetal as a temperature sensing component. When the electrical appliance is working normally, the bimetal is in a free state and the contact is in a closed/open state. When the temperature reaches the operating temperature, the bimetal is The heat generates internal stress and moves quickly, opens/closes the contacts, cuts/connects the circuit, and plays a role in temperature control. When the electrical appliance cools to the reset temperature, the contact automatically closes/opens and resumes normal operation.

It has the characteristics of stable performance, high precision, small size, light weight, high reliability, long life, and low interference with radio.
Widely used in: water dispensers, water heaters, sandwich toasters, dishwashers, dryers, disinfection cabinets, microwave ovens, electric coffee pots, electric cookers, refrigerators, air conditioners, glue machines, office equipment, car seat heaters, etc. Electric heating appliances.
Installation:
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.
