Abstract
An assembly (24) for monitoring the travel of a device includes a potentiometer (26) having a slide bar (32). The potentiometer generates a resistance value according to a position of the slide bar which is coupled to the door through a rotatable member (40) carried by a bracket (34). A slide rack (36) is carried by the bracket and is coupled to both the slide bar and the rotatable member. The slide rack operatively engages the rotatable member between predetermined first and second positions and operatively disengages from the rotatable member when at the first and second positions.
