The Normally Close DC Door Magnetic Switch supplied by ShenZhen Cian Electronics Co., LTD is a compact contact device designed for low‑voltage DC operation. It features an ABS housing that encloses a ferrite magnet and a precious‑metal reed contact. In the normally closed configuration the circuit remains completed until the magnetic field is removed, at which point the switch opens to signal door or window status. This model is listed as a bestseller in the supplier’s catalogue.
The ABS construction provides resistance to impact and chemical exposure, while the ferrite magnet ensures stable magnetic flux across the sensing gap. Precious‑metal reed contacts are chosen for low contact resistance and long life under repeated actuation. In the broader market such switches are commonly rated for 5‑24 V DC operation and a switching distance of up to 10 mm, which matches typical security alarm and access‑control installations. Typical industry tolerances include a temperature range from - 10 °C to +70 °C and insulation resistance exceeding 100 MΩ.
End users include OEM security system manufacturers, B2B distributors, and installers of automatic door detection equipment. The supplier indicates readiness for OEM and ODM projects and can provide bulk quantities for large‑scale alarm system production. Trade terms such as minimum order quantities, packaging options and incoterms are not disclosed in the listing and should be confirmed directly with ShenZhen Cian Electronics. Buyers are advised to request sample units and test reports before committing to volume orders.

Before placing an order, verify the exact voltage rating, switching current and air‑gap distance with ShenZhen Cian Electronics. Request a data sheet that lists the insulation resistance, contact resistance and any certifications such as RoHS that are relevant to your market. Confirm the minimum order quantity, packaging dimensions and whether the supplier can provide custom labeling or branding for your project.
Discuss logistics early: ask the supplier which Incoterms they support, typical lead‑times for bulk production and preferred payment methods. Many Chinese manufacturers work on FOB Shenzhen or CIF major ports, but the exact terms should be negotiated to match your import schedule. Clarify whether the supplier can arrange freight forwarding or if you will need a third‑party logistics partner.
Plan quality assurance steps by arranging a pre‑shipment inspection according to IEC 60730 or your own test protocol. Request sample units for functional testing and obtain a test report confirming contact resistance and insulation resistance values. Ensure that the supplier can provide a Certificate of Conformity and a full test report together with the commercial invoice and packing list for customs clearance.
