ABSTRACT:
A pin protrusion test fixture includes an element having a void therethrough, structure for biasing the aforementioned element in a first direction to a first position, and structure for directing a pin toward that element so that the pin causes the element to move in a second direction to a second position. The test fixture also includes a light source and a light sensor disposed so that when the element is in the second position, light from the light source passes through the void through the element having a void therethrough and is then detected by the light sensor.
