KST401 Radiator Adjustable Bimetal Temperature Switch

Product Item: KST401 Radiator Adjustable Bimetal Temperature Switch
Category: Adjustable thermostat
Material selection of bimetal. Bimetal is a heat sensitive material. There are 145JB1477 made in Switzerland and 5J18 made in China. The performance of these two materials can be tested according to the requirements of the working temperature range of the electric iron, and the performance that matches is selected. If the performance results are almost the same, you can choose an inexpensive one to reduce the manufacturing cost.

  • PRODUCT DETAIL
I believe that many people are no strangers to electric irons, but their understanding of temperature controllers is estimated to be relatively small. Electric iron thermostat is mainly composed of temperature control knob, spring combination, contacts and bimetallic pieces. Next, we mainly introduce the selection of bimetal and spring leaf material for electric iron thermostat.

1. Material selection of bimetal. Bimetal is a heat sensitive material. There are 145JB1477 made in Switzerland and 5J18 made in China. The performance of these two materials can be tested according to the requirements of the working temperature range of the electric iron, and the performance that matches is selected. If the performance results are almost the same, you can choose an inexpensive one to reduce the manufacturing cost.

2. Material selection of reed. The working temperature of the iron thermostat can be adapted to 0 to 260 degrees Celsius. When choosing the material for the reed combination:
The first is that sufficient elasticity can be obtained, and the elastic force generated by it must be maintained at the working temperature for a long time.
Second, the choice of reed material requires strong resistance to oxidation and corrosion. You can choose 0Cr17Ni7Al and 0Cr15Ni7Mo2AL.
