Default Micro switch question

There are known issues with reed switches. They're no longer used in
burglar alarms - they once were - because as well as being electrically
issueful there were so many door alignment false alarms. Yours may be
fine, but so many were not.


It could well be there are problems if they are simply thrown in place.
But that can be said for most things.

I can understand pro alarm installers wanting something simpler, though.
Most pro alarm house installations I've seen have been terrible - with
unprotected wires running everywhere. Often down the side of a fitted
carpet - or just tacked to a skirting board. All done in the fastest
possible way. With surface mount reed switches all too easily damaged.

I did my own install - and took a lot of time and trouble to conceal all
the wiring and switches. And as I've said have had zero problems with them.
