Magnetic Reed Switch

[kd5crs]

I'm looking for a magnetic relay switch (aka dry contact sensor, aka what is wired to a DS10A) with the smallest activation gap. Ideally it would be the rectangular kind.

The ones I see brag about the size of the activation gap, but I'd like one that doesn't close unless the magnetic is just about touching. 1/8" would be perfect.

Anyone know of something like that? Or any way I can shrink the distance a normal reed switch closes at?

Thanks.
Brian

It almost sounds like you'd like an actual contact: I built one out of a spring metal flange and a flat plate. Or do you actually need a gap?

Hmmm, a contact could work. Thanks for the idea! That will probably simplify things greatly.
