Abstract
The invention relates to a method and a device for selectively controlling the lock condition of the doors of a vehicle. The door lock control device includes a set of at least three switch contacts incorporated into a single switch device which allows a user to activate each contact through the use of a single handle. Closure of the three switch contacts provides the user the ability to lock all doors and to selectively unlock subsets of all the doors through the use of the single switch handle. A first switch contact is activated when the switch handle is moved in a desired direction. A second switch contact is activated when the switch handle is further moved in the same direction. A third switch contact is activated when the switch handle is moved in an opposite direction. The second switch contact includes a generally flexible conductive member supported adjacent a printed circuit board.
