Snap
Action Bimetal
Thermostat
Applications
The snap action
thermostat with immediate operation is used in those applications
where the temperature of the device heated electrically must be selected
and adjusted by the user beforehand, as in the case of electrical
irons, deep fryers, electrical heaters or water heaters.
Operation
The temperature
is adjusted by the rotation of the device's axis. When the desired
temperature is reached, the contacts are quickly opened due to the
deflection of the bimetallic strip, interrupting the circuit's power
supply. When the temperature drops, the contacts are closed and the
circuit starts to operate again. These types of thermostats are used
in appliances with a very quick temperature response.
