Overview
The TRS Thermal Reed Switch is a highly reliable, precise
temperature-sensitive switch ideal for energy conservation.
Its unique proprietary design features a magnet and
a temperature-sensing soft ferromagnetic substance
called Thermorite®. The material’s magnetic flux density
decreases as the temperature increases turning it into a
paramagnetic substance at the Curie temperature.
These products have also been attested by the International
Relay Association.
