## Description

Recessed Wired Security Window Gate Contact Sensor Alarm Magnetic Reed Switch Black ,Magnetic Door Sensor, Normally Closed Magnetic Switch Product Name: Door Magnetic Sensor Switch Product color: Black Product size: 29*15.5*9mm Main material: ABS Sensing distance: 10mm-15mm Wire length: 33cm Working current: 0.5A Working voltage: 100V (1-100V) Maximum power: 10W Service life: 1000000 times Product package Door Magnetic Sensor Switch*5 Screw*20 Sticker*10

Review: good item, does detect at 15mm, as described - Good item, works fine, I was a bit worried about the distance for detection, but when I tested these it was almost exactly 15mm distance for detection, which was plenty for me.
Review: Works as expected - Connected these to an ESP32 and then stuck to my door. ESP32 is running ESPHOME which is then connected to Home Assistant. I get instant notifications when the door is open. These reed switches aren't overly sensitive so they do have to be quite close together to actually get the 'closed' signal. They were extremely easy to setup and good value for money.

### ⭐⭐⭐⭐ Good value for money
*by S***N on 29 June 2020*

These arrived very promptly next day. The five switches and magnets were nicely packaged in a wee plastic box. Screws and sticky pads were included to give alternative fixing methods. The switches have insulated leads of around 30cm in length and at the end the leads are bared and tinned. They seem to work well with the switch operating when the magnet is at a distance of around 10mm. The are described as normally closed but, to me, this was a bit misleading, so I tested them. When there is no magnet the switch is open (non conducting). When the magnet is close the reed switch closes and conducts. I would call that normally open but I suppose it depends on your view of what is normal.
