Working Principle
When the electrical appliance works normally, the bimetallic sheet is in the free state and the contact is in the closed / open state. When the temperature reaches the operating temperature, the contact is opened / closed, and the circuit is cut / closed, so as to control the temperature. When the electric appliance cools to the reset temperature, the contact will automatically close / open and return to the normal working state.
Advantage
Thermal switch has the characteristics of stable performance, high precision, small volume, light weight, high reliability, long service life and small radio interference.
Easy to Installation
The flange on the switch is float and easy to installation.
Please Note
1.Do not collapse, loosen or deform the top of cover surface during installation to avoid affecting performance.
2.Do not allow liquid to penetrate into the interior of the thermostat or crack the housing.
3.The thermostat should be stored in a warehouse with RH less than 90% and ambient temperature less than 40 ℃, which is ventilated, clean, dry.

I thought this went out on my 400w fog machine. The unit on my machine was 208 degrees and the closest I could find was this 210. The problem was really the thermal fuse that is embedded in the frame underneath the heat exchanger. Once that was replaced the machine came to life. However Im glad to have these in my box of fogger supplies.

We have 3 oil heaters, one of them quit working. Instead of buying a new one we order these parts, it took over a month to receive them. My husband replaced it and our heater works like a charm!! These heaters cost anywhere from $45 to over $100

I used it to modify a sandwich griller. It used a thermal snap disc which opened at 210 degrees, so it barely grilled the bread. Replaced with this, it now does an excellent job, and stays within 415 to 475 degrees Fahrenheit.

Used this to replace a fried one in a microwave and saved us some money on buying a new one. Works perfectly now. Couldn't find one with a matching model number, but I think it doesn't matter so much as long as you match up the temperature rating on it.

Worked perfectly. Used them to repair a home steam press that the original thermal switches had failed open on. It's back up and running again.Best price for the switches I could find.If they die in a short time window I will update the review.

Les connecteur étaient un peu plus gros que ceux d'origine, je les ai coupé pour pouvoir utiliser les fils d'origine.Maintenant mon grille à panini fonctionne comme un neuf.

It’s a miracle ! Bought a Jennair Steamer Oven JBS7524BS , 6 years ago . Was on open box . Never knew it had been refurbished . The oven never worked right and kept shutting off after 10 min. After hours of research realized the Temperature Limit thermostat was replaced with 115 Celsius or 230 F WRONG part . Bought this 250C/ 482F part and bingo …. FIXED!!!! If your appliance is tripping off …. Fabulous fix and you get a few extra. Super pleased !!!!
