Trying to read between the lines and come up with something that is
plausible here is my guess.
Some very different contact that has a magnet built in so that when the
metal plate was in position the magnet was attracted to in thus causing a
set of contacts to be opened or closed inside the device.
Never heard of such a set up. Might work on a metal door, but doubt it.
Would not ever install one even if it was free. Could be from a parallel
universe that brushed too close.
Take pictures and post somewhere for all to see.
