I hate door jamb switches. As far as line voltage, since splices must be in a junction box, you get an impressive piece of metal to mortise in, I know of no other alternative. As you know, low voltage allows for smaller parts but has added costs for transformers, boxes and relays.
I know of no other methods that are economical, I always try to talk customers out of door jamb switches.
