Bimetal Switch

Bimetals from the basis of the BTS .Temperature sensing is carried out by a bimetal, which snaps over when the nominal switching temperature (NST) is reached.
On cooling back down to reset switching temperature (RST), the switch returns to its original state.
The bimetal in the model BTS bimetal temperature switch carries no current, and this eliminates the possibility of arcing.
The rest switching temperature is approximately 10-20°C below trip temperature.
