And almost never been discussed that this magnetic lock is so suitable to be used at share toilet (two rooms with one share toilet). Place as that at the two doors, supplied by 12v regulator while the switch is placed at any suitable location inside the toilet, soon as someone enter from anyone room, swith on, both the magnet active to lock the doors. No normal manual lock is required at both doors inside since that is usually the problem cause when the user forget to unlock the other door from inside, i guess all understand.
