## Description

desertcart.com: Magnetic Reed Switch,Normally Closed NC Waterproof Magnetic Switch,Micro Alarm Reed Switch 10W 100v 0.5A Magnetic Door Sensor Switch to DC 5V 12V 24V Lights（2 Pack） : Industrial & Scientific

Review: Work Great! - Used these to activate lighting (12v COB LED) inside a storage compartment so that lights were only on when the door was open. Spliced the wires in and it works flawlessly. I used the included adhesive mounting strips to position and test the position of the two halves of the switch on the door and frame. Secured more permanently with screws once I confirmed functionality but installation was easy and it’s a cool feature to add to a lighting project.
