Looking for a door-contact device.

[123]

I want to make an electrical connection to a PowerBolt deadbolt lock mounted on a door. I'm looking for a device I saw somewhere on Cocoontech but can no longer find it!
I can run wires from my M1 to the door-frame and wires from the deadbolt to the door-edge ... but bridging the gap is the challenge. I saw a gadget that can do the trick. One half of it mounts on the door frame and the other half is installed on the edge of the door (where the hinges are located). Each half has two electrical connectors. When the door is closed the two halves make contact.

Anyone know what I'm talking about and where I can get one?

ADDENDUM
Well, I found it here. Anyone know where to get these things?

Very good question, was wondering this myself.

Check out these hinges that are wired to allow electrical power through them:

Only problem is they appear to be close to $200!

It took me a little bit to remember and search but they are actually from the automotive industry. TAC TWO Jamb contacts

Thanks for the lead, mustangcoupe! I would not have guessed to look for an automotive part.

Mitch, I considered using the existing door hinges. I don't need to pass any current through them (wow, that would be a bad idea) but simply short them. The Powerbolt lock has two sets of contacts. Momentarily short one set and the deadbolt extends. Short the other set and the deadbolt retracts. The two sets share a common contact so you need three wires to control the lock. The door has 3 hinges so, in theory, I can use them as conductors to control the lock. It seemed like a hack ... until I saw the commercial versions!

beat me to the automotive part... I remembered those because my old suburban used those for the door locks in the rear - you can also get them from Jegs.

As far as the drilling if you went that route, I'd think you'd want a really steady hold from the hinge side straight through to where the electronics were - and then routing the hinged-edge to get up or down to the hinges... being just a ground, that's actually a pretty decent idea!

You read my mind! I've got a spinsaw with a router-base that should let me do a neat job. This is a foam-core, steel-faced door so getting the wiring through the door shouldn't be too difficult.
