Abstract
A seat belt retractor for motor vehicle applications having a switch assembly for controlling a seat belt warning indicator or other electrical circuits requiring an input of belt webbing extension or retraction. The switch assembly includes a cam disk which is rotatable with the retractor spool having generally spiral grooves on one of its radial face surfaces. A follower, made of an electrically conductive material, engages the grooves and is moved radially in response to the rotated position of the spool. When the follower reaches a predetermined radial position, the follower engages the electrical contacts, thereby closing an electrical circuit.
