A compact reed switch module that closes its circuit when a magnetic field is present. Inside the glass envelope, a pair of ferromagnetic metal contacts come together when a magnet is brought close, and spring apart when the magnet is removed — providing a simple, contactless switching mechanism.
Key Features
- Magnetic Activation – Closes circuit in the presence of a magnetic field
- Normally Open – Contacts are open when no magnet is present
- Compact Size – Mini form factor for easy integration
- No Power Required – Passive component, no operating current needed
Ideal For
- Door and window open/close detection
- Proximity sensing with magnets
- Security alarm systems
- Arduino and microcontroller input projects
Package Contents
- 1× Mini Reed Switch Module
