Abstract
A door switch disclosed includes a switch body and a key unit which are attached to a structure and a door, respectively. The switch body is provided with a door key insertion hole and a switch contact. The key unit has a door key and a door key drive mechanism in its unit case. The door key drive mechanism retreats the door key into the unit case when the door is opened and protrudes it out from the unit case when the door is closed, to thereby insert the door key into the door key insertion hole in the switch body, thus turning ON the switch contact.
