"A friend gifted me an old 3-gallon horizontal air compressor that had a broken on/off switch. I removed the switch, confirmed that it was a common KCD2/KCD4 configuration, found this corresponding item on Amazon at a great price, and now the compressor runs like a champ!" [2]
"Tech support cross referenced OEM part number and sent me this switch. First of all it was a 5 terminal switch, and mine was a 4 terminal switch. Secondly, when I did hook up the harness with the switch in the off position, the starter motor engaged. It was configured wrong for my application. I would suggest doing a bit of research before just buying." [2]
