KSD301-V Bakelite Auto bimetal high temperature limit switch from FSTB(1/2")
KSD301-V series snap-action thermostat is a kind of miniature hermetically sealed bimetal thermal switch (1/2" disc). It is of single-pole single-throw structure and works under resistive load. KSD301 thermostat is in wide use in a great variety of compact type home appliances, such as coffee maker, water dispenser, toaster, microwave oven, electric pad and portable icebox etc., to provide temperature control or temperature protection.
Advantages:
- Easy mounting.
- Rapid heat transmission.
- High durability.
- No breakdown, no flashover.
- Every product will be tested, extremely high temperature pass rate.
- High precision.

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.
Covers and terminals:
