About This Product
Need to monitor when a door or window opens?
This little magnetic reed switch is a simple, reliable way to do it.

It's a normally closed type, meaning the circuit is complete when the magnet and switch are together – and when they separate, it triggers.

The sensing distance is about 23 to 35mm, so it's pretty forgiving on installation.

Made with a zinc alloy shell that's sturdy and corrosion-resistant, with silver finish that looks clean.
Handles up to 10W, 100V, and 0.
5A – plenty for alarm systems, automation projects, or commercial security setups.

Comes with 320mm of 24AWG wire attached, so you've got some slack to work with.

Weighs about 43g – feels solid.

Great for metal doors, windows, gates, anywhere you need a reliable open/close indicator.

Works like a charm.
