## Description

Differences of NC, NO, NC/NONormally Closed(NC): When the switch is close to the magnet, the circuit is conductive(light on); when the switch is separated from the magnet, the circuit is not conductive(light off).Normally Opened(NO): When the switch is separated from the magnet, the circuit is conductive(light on); When the switch is close to the magnet, the circuit is not conductive(light off).NC/NO Combined: The switch has 3 contact types: NC/NO/COM, you can choose to connect two of the contacts(NC-COM or NO-COM).PLEASE NOTEA magnetic door contact can only provide a switching signal to the device. It cannot directly load the power supply and cannot be directly connected to the lamp.Specifications:Model: MC-38Contact Type: NCMaximum Sensor Sensitivity: 10-20mmLoad Current: 100mAWithstand Voltage: DC 0-36VWorking Voltage: DC 0-24VMounting Hole Distance: 18mm / 0.71inchSize(Approx.): 27 x 14 x 8mm / 1.06 x 0.55 x 0.31inch (L*W*H)Each Wire Length(Approx.): 30cm / 11.8inchWire Type: 1007#/24#320mmULHousing Material: ABSPackage Content: 5pcs x Magnetic Door Switch20pcs x Mounting Screws

Review: Works flawlessly - I recently installed these sensors for a remote garage door project, and I’m really impressed with their performance. These sensors (MC-38 model, 5-pack) are exactly what I needed. The sensors come with adhesive paper, so you can easily mount them on doors or windows without any drilling or hassle. I used the adhesive to install the sensors and everything stuck securely in place. The wires are long enough to give you flexibility on where you want to connect them, and the surface mount design makes it easy to attach them to any flat surface. The magnetic reed switch works flawlessly. When the door opens, the circuit breaks, triggering action. The response time is quick, and I’ve had no issues with false triggers or malfunctions. The build quality is solid for the price. The sensors are compact yet durable, and the adhesive backing holds up well over time. I’ve had them installed for a few months now, and they’ve remained firmly in place, even on a garage door that is opened and closed frequently. For a 5-pack, the price is fantastic. These sensors offer excellent value considering the price point.
Review: Works great! - Great value for the price These are very durable as I used them on my truck's tailbed to turn on and off LED lights.

Great value for the price These are very durable as I used them on my truck's tailbed to turn on and off LED lights.

### ⭐⭐⭐⭐⭐ Small, Compact, Reliable and super-sticky! Great adhesion!
*by A***R on July 7, 2023*

I purchased the NC version of these switches. (ie: Normally Closed with magnet near the switch.) These fit the bill and were exactly what I needed. The small size made them easy to install discreetly. There wire leads were long enough to work with (I needed to extend them with additional wire, but they were easy to connect with butt-connectors (crimp style). Switch is reliable and the magnet is strong enough to be able to activate the switch even when not touching. Screws are provided for affixing to most surfaces, however on my PVC (plastic) window frames, the self-adhesive backing is VERY strong and adheres well. (Just make certain to clean the surface with rubbing alcohol to remove any dirt and oils. NOT windex, that leaves a film... only alcohol will work.) --- Three purchases of this item so far! If I need more, I'll be back.
