China Custom Limit Disc Thermostat Control Switches Therm o-Disc
Snap Disc, or 3/4″ Limit switch thermostats (KSD301/KSD302/KSD304/KSD308) are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” from a convex to a concave shape at a set temperature. carrying up to AC 110V/400V, 10A-60A amps-240 Volts, Action mode: automatic reset, manual reset (normally open/normally closed).
Snap Disc, or 3/4″ Limit switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” from a convex to a concave shape at a set temperature. carrying up to AC 110V/400V, 10A-60A amps-240 Volts.
Limit Disc Thermostat Control switches are the same for different stoves, Electric ovens, electric water heaters, 전기 히터, household appliances, 모터, refrigeration or heating equipment. so to replace it cheap you just have to understand their function.
Why are they called Snap Discs Limit Thermostat is because they are round like a disc and have a Bi-Metal Strip that Snaps when heated to a certain temperature!
Most Limit Disc switches are SPST Thermostat single pole single throw. This means one wire in and one wire out. So when the temp rises the wires are connected which means the switch is closed ( Equipment power outage ).
It will also keep the fans running after the Electric oven / electric heater has been manually or automatically turned off until the exhaust temperature cools down. Unless it is like the Disc Thermostat which has another identical switch just like it to keep the fans running. Sometimes they have a part number with a designation F for Fan or L for Low Limit but don’t be fooled they are the same type of switch! After all you can test it with a continuity checker or ohm meter. When the switch is cold the meter should read open or infinity on the ohms scale and when heated above 140 Degrees F the switch will close and read a short or no ohms Usually a bad low limit switch means the Electric oven, electric heater stops running after the 15-20 min Electric oven, electric heater start-up cycle.
Also the part numbers for each Electric oven, electric heater manufacturer may differ.
Since most open when the exhaust temp drops below 140 degrees f the part number may be called L140 Also they close when the exhaust temp rises above 140 degrees f or 150 degrees f so they may be called F130 or F160 Let’s get real here folks these Limit Disc switches are not fully digital with precise accuracy!! So 130 or 160 may be within the specs of the bi-metal strip inside meaning there are the same switch!!
So in the pic here below is one that I found cheap. Note the physical mounting is usually the same with the mounting holes 2 inches apart. Most Electric oven, electric heater have a male quick disconnect terminal but some Electric oven, electric heater like YAXUN who make their own switch have screw terminals. However the screws can be removed and a clip can go on it but they do charge more for the extra unnecessary hardware!!

Bimetal Overload Thermal Protection for Three /Single Phase AC/DC Motor
Hi-Amp motor bimetal overload thermal protection switch are installed in motor circuits, and the current going to the motor passes through the bimetallic tripping element. The most salient feature of 17AM / KSD9700 / TB / 6AP/ 3MP/ 5AP series thermal overload switch / motor thermal protection switch is small volume and large current carrying capacity.
Replacement Hi-limit Cut off Thermostat & Resettable Thermal Switch
KSD301, KD302, KSD306, KD308 Hi-limit Cut off Thermostat & Resettable Thermal Switch When the circuit is working properly, the contacts are in a closed state. When the rated operating temperature is reached, the bimetal is deformed by heat and breaks quickly, cutting off the circuit. After that, the device begins to cool down.
