The vehicle door latch includes a housing having latch bolt rotatably mounted for engagement with a striker mounted on the door jamb. The door latch includes a detent mechanism adapted to establish the latch bolt in rotary positions to selectively latch the door in a primary closed position, to latch the door at a secondary door ajar position, and to unlatch the door at an unlatched position allowing door opening movement. The electrical switch includes a rotor rotatably mounted on the latch housing and carrying a first set of electrical contacts adapted upon rotary movement of the rotor to electrically connect with a second set of electrical contacts mounted on the latch housing. The rotor and the latch bolt each have gear teeth provided respectively thereon and meshing with one another whereby rotary movement of the latch bolt induces corresponding rotary movement of the rotor and thereby enables the switch mechanism to provide electrical signals corresponding to the various positions of the latch bolt.

In combination with a vehicle door latch having a latch bolt rotatably mounted upon a latch housing for rotary movement to selectively latch and unlatch a door, an electrical switch mechanism associated with the door latch comprising: a switch housing of molded plastic mounted on the latch housing and having a switch cavity therein; a first plurality of switch contacts mounted on the switch housing in the switch cavity thereof; a switch rotor; a second plurality of switch contacts mounted on switch rotor; means rotatably mounting the switch rotor on the switch housing so that rotary movement of the rotor electrically connects and disconnects the first plurality of switch contacts with the second plurality of switch contacts; a plurality of gear teeth provided on the latch bolt; a gear sector having gear teeth thereon; means rotatably mounting the gear sector on the switch housing with the gear teeth of the gear sector meshing with the gear teeth of the latch bolt whereby rotary movement of the latch bolt rotates the gear sector; drive means connecting the rotor and the gear sector whereby rotary movement of the latch bolt induces corresponding rotary movement of the rotor and thereby enables the switch mechanism to provide electrical signals corresponding to the positions of the latch bolt; and a molded plastic cover mounted upon the plastic housing to seal the switch cavity against the entry of foreign matter therein.
