I'm looking for a 3-position switch for a door with a magnetic lock. The positions will keep the door locked, keep the door unlocked and unlock the door momentarily. i found the exact switch that I need from Doorking (pictured below) except that it's designed for electronic locks, not magnets. The switch I need has to have it's momentary position cut the power from the magnet, not provide power like door strikes need. I've been looking everywhere with no luck. Any help appreciated.

Maybe of combo of 2 switches wired in series.

For a button to keep door unlocked :

Something to keep in mind is that both door strikes and magnetic closures come in two type, fail safe (loss of power = unlocked) or fail secure (loss of power = locked) depending on the application.

Check with Craftmaster hardware 800-221-3212, someone there can probably help you with locating exactly what you need.

Maybe I'm being old fashioned, but when a switch didn't do what we wanted it to do we wired it to a relay (or 3) and made it work.

You would normaly use a "request to exit" momentary button that is SPDT so you can wire it any way that you want. For the hold open you would use a key switch which is again SPDT. Don't know what kind of security this would provide if anybody can just walk over and flip a switch to keep the door unlocked. Both are readily available from security dealers like ADI.

That's what we ended up doing.
