Niche but Essential Normally Closed Relay
By connecting the coil circuit of the Foocles normally closed relay in series with the alarm device, the circuit closes and triggers the alarm in the event of a power failure. This design ensures that the alarm will be triggered even if the power is not intentionally cut off. We welcome customers with specific needs to contact us for a quote.
Normally Closed Relay Series
Key Strengths of Normally Closed Relay
Our normally closed relays can either cut off power or trigger an alarm for any fault that causes a circuit break.
Due to the long-term closed state of the NC relay, components such as coils and contacts rarely suffer wear from operation.
The two circuits of normally closed relay can be connected in series to two devices to implement a “NOT” logic function.
Foocles normally closed relays can trigger an immediate power cut through extremely rapid response, ensuring system safety.
Normally Closed Contacts for Safety
Normally closed relays have a highly specialized “Fail-Safe” application. For instance, when used as GPRS relays for remote control, if the communication module or MCU ceases operation, the relay contacts automatically close. We must design this state as the safe condition to prevent potential hazards and subsequent accidents when human intervention is unavailable. You can purchase Foocles normally-closed(NC) relays to ensure the safety of your equipment.
More Accurate Status Prompts
We can connect a Foocles normally closed relay contact in series within the device’s circuit and attach an indicator light to promptly detect whether the device or circuit is energized or de-energized. This can help us save a significant amount of troubleshooting and maintenance time. Develop the phenomenon of “power loss” into a clearly defined, controllable state.
Prevent adverse consequences caused by power loss in the relay coil circuit due to equipment power failure, system crashes, signal loss, or similar events.
High Quality Material Normally Closed Relay
Normally closed relays also be called JD1915 Relay typically have their coils de-energized, resulting in relatively longer electrical lifespans for both the coil and contacts. Nevertheless, we steadfastly adhere to the principle that quality is the ultimate measure of success in manufacturing relays.
Even after years of oxidation and other effects, the coil can still rapidly engage the contacts when energized.
Maintains stable product characteristics and prevents long-term power-on contact erosion.
It can better handle electrical current and heat, extending its service life.

Yes, we can provide OEM ODM OBM for you.
In locations where circuits do not need to be frequently switched on and off, and where certain safety requirements exist.
You can call our sales team directly—they’re always ready to assist you. Alternatively, you can leave us a message, and we’ll get back to you as soon as possible.
Relays differ in their de-energized states; normally closed relays can guide circuits into a safe state when deactivated.
Simply permit the circuit diagram connections on the relay.
When not energized, the relay contacts remain closed at all times.
