A test fixture for determining proper or improper insertion of a pair of contact pins from a circuit component through a pair of mating sockets in a circuit board. The fixture includes a support frame mounted beneath and supporting the circuit board. A detection member is movably mounted on the support frame beneath the pair of sockets for engagement by the contact pins upon proper insertion through the sockets. The detection member is movable from a first position whereat neither contact pin is in engagement therewith, to either a second position in response to both contact pins coming into engagement with the detection member or a third position in response to only one contact pin coming into engagement with the detection member. A signal device directs a light beam across the path of movement of the detection member for rendering a signal only when the detection member is in the second position whereat both contact pins are in engagement with the detection member after proper insertion through the sockets in the circuit board to move the detection member to its second position.
