I started to put some power panels together and I realized the snap in plug units I bought don't work in a panel thicker than 1.8 mm. I had the panels made with 2.5 mm stock. I found I could modify the snap in units, but I don't like the modification. I found some other screw in plug/switch combination units that are 0.5 mm bigger (about 0.020 inches). I bought some hoping they will fit with little if any filing needed for the existing openings. I can drill the mounting holes with little difficulty if they fit the openings.
I still haven't been able to make time to stuff a PCB. Oh well. Maybe Sunday or Monday evening.
