Magnetically-activated reed switches for simple contactless position and door/window sensing.
Reed Switch
Reed Switch Module
45,00 EGP- 🧲 Reed switch module for magnetic sensing
- 🔁 Detects magnet presence (open/close switch action)
- ⚡ Digital output—easy to read with Arduino/MCU GPIO
- 🛠️ Simple 3-pin interface: VCC, GND, OUT
- 🚪 Ideal for door/window sensors and security alarms
- 🧩 Great for position sensing, counters, and limit switches
- 📦 Compact module—breadboard friendly
- ✅ Perfect for smart home and DIY automation projects
A reed switch closes its contact when a magnet passes nearby, offering an extremely simple, low-cost way to detect a door or window opening, or to build a basic magnetic proximity sensor, without any active electronics involved in the sensor itself.
