Gebildet 5-Pack Recessed Wired Magnetic Reed Switch – Normally Closed, 10-15mm Sensing Distance, 33cm Wire, For Windows & Gates (Black)

About This Product

Looking to add some security to your windows, gates, or doors?

These Gebildet recessed magnetic reed switches are a simple and reliable way to do it.
They're normally closed – meaning when the magnet is near, the circuit is connected; when the magnet moves away, the circuit breaks and triggers your alarm.

Classic and effective.

Each switch is tiny – just 29 x 15.
5 x 9 mm – so they recess neatly into frames without sticking out like a sore thumb.
The sensing distance is about 10 to 15 millimeters, so you don't need perfect alignment, just close enough.

Wire length is 33 centimeters, giving you some wiggle room for installation.

These handle up to 0.

5A current and 100V (1-100V) with a max power of 10W.
They're rated for a million operations, so they'll last a long time.

The body is black ABS plastic, tough and unobtrusive.

You get 5 switches, 20 screws, and 10 stickers in the pack – everything you need to get them mounted.

Great for DIY alarm systems, gate monitoring, or any project where you need to detect if a door or window is open.
Simple, effective, and affordable.
