replacement switches for existing alarm system
nothing lasts forever. Our alarm became faulty and I traced it back to faulty door and window switches. (after 26 years can't complain) easy to fit replacements but?check switch function "before" fitting. I had 2 new ones that didn't work properly. the very tiny switch failed to respond to the magnet. As they were cheap enough I just ordered some more. Job done

Brilliant quality and super easy to fit
Alarm monitoring company had quoted £70-£100 to supply a new sensor. Double pack from Amazon for way way less!! Now that’s value for money. Fitted in just a few mins by watching some YouTube videos. Great!

Good replacement parts for the price
Bought to replace a 20+ year old sensor that had failed. Arrived quickly, was easy to fit, worked straight away, and had another spare left over for less than a fiver. No instruction leaflet supplied, but the alarm connection instructions are on the product description.

They work as expected
I tested these door contacts and they work as expected at a good price.Unfortunately they aren't a drop in replacement for my old door contact which has a few resistors and a switch inside it too. So double check what's actually inside your door sensor before buying a replacement :)
