ABSTRACT:
An array of reciprocating rods are aligned with circuit board lead apertures and are normally biased to engage the printed circuit board apertures. When leads are present the rods abut the leads. Circuit connectors attached to the rods close a circuit path when a missing lead is sensed. When one or more of the leads of a given component are missing, a circuit is closed and an indicator lights.
