What's the difference between N/C and N/O
Normally Closed: When the temperature falls to the reset temperature, the
thermostat contact can be connected again. (If the reset
temperature is not reached, the thermostat contact is also
disconnected)
Normally Open: When the temperature falls to the reset temperature, the
thermostat contact can be disconnected again. (If the reset
temperature is not reached, the thermostat contact is also
connected)
Please Note :
- During installation, the temperature switch should be completely
close to the mounting surface of the tested appliance.
- Do not collapse or deform the plastic / metal shell during
installation.
- For metal temperature controller, when using, do not remove the
insulating sleeve to avoid electric leakage. Not suitable for
working in water.
- Not suitable for air temperature sensing, only applies to contact
sensing.
