ABSTRACT:
A door-ajar switch assembly for a door movable between open and closed positions relative to an opening in a vehicle body. The switch includes a housing supported adjacent to the opening in a position of inward and outward adjustment. An actuator projects outwardly from the housing and is retractable inwardly to a switch-actuating position. A switch operator is mounted on the door and moves the switch-actuator to the switch-actuating position when the door is closed. The switch operator has an actuator-engaging front face. An adjustment member is secured to the front face of the operator to engage the actuator when the door is initially closed to retract the actuator beyond the switch-actuating position and push the housing inwardly to an adjusted position. The adjustment member is made of a water-soluble material and dissolves away when subjected to water treatment, leaving the front face of the operator to engage and to retract the actuator to its switch-actuating position when the door is subsequently closed.
