I need help in designing a circuit to test for missing connector pins
Unit to test is a 25 pin molded connector, I have built a test box and installed 25 spring loaded test probes that align with the connector pins
the switch probes are normally open until compressed then conduct current through to the bottom socket of the probe where I have attached a wire to each one, My idea was to send 24v to the first switch probe if it is compressed that means the pin in the connector is present and will allow the current through the attached wire to a relay switch then back up to the next switch probe and next relay switch and on through all 25,
pins.... if all pins in the connector are present the current will continue through to activate two solenoids one that allows the lid to open and one that will do a punch to mark the part as tested, and also lite a led as a
pass test... if the test fails that would mean a pin is missing in the connector and the lid latch will stay locked till a override key allows the lid
latch to open.... As I am more mechanical then electronic I could use all the help I can get... I can send pictures of the mechanical unit I have built... <SNIP>
