Check that the switch supports your LED lighting system voltage. Some models work at 3V or 12V while others accept up to 24V.
Always match the switch rating to your power supply to prevent failure.
Contact Type
Decide between Normally Open or Normally Closed configurations based on your alarm logic.
Combination packs offer flexibility to switch modes freely.
Mounting Options
Look for included screws or adhesives for easy installation.
Recessed designs require drilling but provide a cleaner look.
Durability and Material
Plastic ABS shells resist impact while glass reeds offer reliability.
Industrial models often feature metal connectors for longer life.
Transmission Distance
The gap between magnet and switch must stay within limits.
Typical ranges are 10mm to 20mm for standard models.
Pack Quantity
Packs range from two to twenty units depending on needs.
Choose bulk packs if covering multiple doors or windows.
Wiring and Connectors
Some use colored wires while others use M8 connectors.
Ensure the connector matches your control system.
Environmental Protection
Waterproof models exist for outdoor or damp locations.
Indoor units may not have the same level of protection.
How to Use and Care for Your Magnetic Switches for LED Lighting
Place the switch and magnet on opposite sides of a door or window frame. Ensure the gap aligns with the trigger range.
Wire the switch in series with your LED circuit or alarm system. Follow the color codes to identify common NC and NO terminals.
Test the switch by moving the magnet away to verify the light turns off or alarm sounds.
Frequently Asked Questions
What is a magnetic switch used for in LED lighting?
Magnetic switches allow touchless control of LED lights by detecting a magnet. They are ideal for security systems and smart home automation.
Can magnetic reed switches work with 24V systems?
Yes many models support up to 24V DC. Check the specific voltage rating to ensure compatibility with your power supply.
Are these switches waterproof for outdoor use?
Some products are specifically waterproof but most standard ones are indoor only. Verify the product description for weather resistance.
What is the difference between NC and NO?
