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
