Abstract
A switch assembly is provided for use in sensing a seat belt spool condition in a seat belt retractor assembly. Features of the switch assembly are a switch housing in which is mounted a conductive member which forms both a fixed contact and a male terminal at its respective ends, a movable contact element which is supported for selective wiping contact with the fixed contact end of the conductive member, and actuating means which moves the movable contact element into wiping contact with the fixed contact end of the conductive member in response to a predetermined amount of seat belt webbing being stored on the spool of the seat belt retractor and which permits the movable contact element to move out of wiping contact in response to a predetermined amount of seat belt webbing being removed from the retractor.
