Has anyone seen this door switch and know of a source / make / model number for them... Unlike the conventional door "hinge" switch that requires cutting into the door frame. This one utilizes a magnetic reed switch "Alarm Contact" which feeds up to a relay that switches the 120 volt AC My old employer started to utilize them and much easier to install and cleaner looking.
A friend of mine just did get back to me with the info I needed. It does utilize a conventional contact switch "which is installed in the door frame" but then low voltage conductors lead from that contact switch to just outside of a standard single gang electrical box where you would have your power in and switch leg run to the closet fixture. The relay device by LVF Inc. called a "TimeSaver CR-120" is installed at that box. You use a handy box cover with the 1/2" K/O The relay gets installed kind of like a door chime transformer so the low voltage wire from the contact switch stays on the outside while the high voltage portion stays in the box. Over the years I had installed dozens of the standard mechanical switches that require cutting "chiselling" into the door frame. On custom homes where they often had door frames of exotic woods, you can imagine how hesitant I was to do this and often required the general contractor to have that part done. With the device mentioned above it is simple as can be. You can also install them on bi-fold and pocket doors very easy. I just ordered some and at around 18 bucks each with the required contact switch, much cheaper than the old alternative "hope I don't sound like a sales person for the product" For those that must acivate a light when a door is opened "can easily make it so light is only on when door is closed also" these are good as gold.

Those work in the exact same way, but for about twice the price. Granted you must purchase 10 of the CR-120V's for 16 bucks each with free shipping. With ether switch you can get very creative as any low voltage "alarm" type contact works "Ball, Plunger, 3/8" or 1/4, Wide Gap .... It is almost endless. You can even use preasure pads on floors / steps where a door not need be opened. Would also be a very cheap method of turning on lighting when an alarm is activated.
