Description
The Reed Switch is a magnetic proximity sensor that closes its contacts when exposed to a magnetic field. This Normally Open (N.O.) type remains open until a magnet is brought nearby, making it ideal for door/window sensors, security systems, position sensing, and DIY electronics.
✅ Key Features:
Normally Open (closes when magnet is near)
Simple, passive magnetic sensing device
Fast response and long mechanical life
Compact glass capsule design
Ideal for alarms, smart homes, and automation
