Reed Switch 2×14mm Normally Open Magnetic Sensor

🧲 Simple & Reliable Magnetic Detection

The 2×14mm Reed Switch (Normally Open) is a compact and highly sensitive magnetic sensor designed for detecting the presence of a magnetic field. When a magnet is brought near, the internal contacts close, allowing current to flow — making it perfect for contactless switching applications.

👉 Ideal for security systems, automation, and DIY electronics projects.
