Discover the Power of Temperature Control Switches! Normally open and normally closed temperature control switch are selected to use according to the actual requirements. Unleash the potential of your system with normally open temperature control switches and embrace maximum flexibility for your applications! Experience the reliability and safety of normally closed switches, offering peace of mind when it comes to temperature regulation.
Normally open and normally closed temperature control switch are distinguished according to the different working state and trigger mode during temperature control.
Normally open thermostat (Normally Open, NO): the switch is off when the temperature is lower than the set temperature; the switch is closed when the temperature is above the set temperature. That is, the switch operates only when the controlled system temperature exceeds the set threshold.
Normally closed thermostat(Normally Closed, NC): the switch is closed when the temperature is below the set temperature; the switch is open when the temperature is above the set temperature. That is, the switch will operate only if the temperature of the controlled system is below the set threshold.
Therefore, in practical application, it is necessary to choose the normal open or normal closed temperature control switch according to the specific requirements of the controlled system. For example, normally open and normally closed temperature control switch are selected according to actual requirements. Here are some examples:
1. Refrigerator: usually use the normally closed bimetal thermal switch. When the internal temperature of the refrigerator rises, the closed temperature control switch will break, and the refrigeration system will reduce the temperature; When the temperature drops to the set value, the closed bimetal thermal switch will close and stop the refrigeration system.
2. Heating: usually use the normally open thermal protector. When the room temperature reaches the set value, the normally open thermal protector will turn off the heating; and when the room temperature drops below the set value, the normally open thermal protector will close and start the heating.
3. Water heater: usually use a normally closed temperature control switch. When the water temperature rises, the closed temperature control switch will break the circuit and stop heating; when the water temperature drops below the set value, the closed temperature control switch will close and start heating.
According to different products and specific requirements to choose the use of normally open or normally closed temperature control switch.
