A customer came to Paragon with a switch plate assembly consisting of several custom, lighted switches wired together and terminating into a 12 position plug. The LEDs which illuminated the switches would frequently stop working and would present random false illumination issues. Activating one switch could cause the LED on a different switch to light. The switches themselves would also seem to activate intermittently without having been pressed.
Several years ago a potential customer contacted Paragon regarding a large wire harness that was responsible for $15K to $20K per month due to the component’s failure rate and volume of service calls. Paragon reviewed the assembly and determined the issue was not the supplier of the harness it was the design of the unit.
