Grab 10pcs N/O Reed Switches at $3.23 – Perfect for Arduino Projects!
Are you looking for a cost‑effective and reliable magnetic sensor for your next DIY or professional electronics project? These 10pcs N/O Reed Switches offer just that—plus an unbeatable price of only $3.23 per pack.
Key Features
- Normally Open (NO): The circuit is open until a magnetic field triggers closure.
- 14 mm diameter: Compact size, ideal for tight PCB layouts.
- Low voltage operation: Works great with 3‑5 V logic, perfect for Arduino and Raspberry Pi.
- 10‑piece bundle: Great value when you need multiple switches for multi‑sensor setups.
- Fast response time: Real‑time magnetic detection with minimal lag.
- High reliability: Durable construction for long‑lasting use.
Why These Reed Switches Matter
- Versatility: Use them for proximity sensing, door/window alerts, or as a simple magnetic switch in robotics.
- Easy Integration: Just wire the two terminals to your microcontroller’s I/O pins and a magnetic core.
- Affordability: At ~$3.23 per 10‑piece pack, you can experiment without breaking the bank.
- Proven Track Record: Over 2,000 units have already been sold—customers appreciate the value and performance.
Quick Start Guide
- Connect one terminal to the ground pin on your microcontroller.
- Connect the other terminal to a digital input pin with an optional pull‑up resistor.
- Place the magnet close to the switch. The input will change from HIGH to LOW (or vice‑versa depending on wiring).
- Write your Arduino sketch to handle the signal.
