Apparatus for testing printed circuit boards

A track section for a slot track racing game has a double walled box channels formed by alignment projections and receptacles therefore on each of the opposite sides of a track. A pair of hooks prevent accidental disconnection of the track sections responsive to random movements. The hooks have dependent fins which concentrate bending forces to the root ends thereof to preclude random bending under stress conditions. A lap counter gives a signal after a slot track vehicle has made a predetermined number of laps.
