Abstract
There is described a motion control device for preventing free-fall of electronics modules during vertical movement into or out of a supporting structure. The system comprises a rotatable element on the module or structure engageable with surface on the structure or module, respectively, for rolling movement therealong. The rotatable element is provided with a clutch or brake to provide resistance to rotation at least when the module is moving downward relative to the structure. The rotatable element may be a gear engageable with a toothed rack, or a friction roller engageable with a friction surface.
