you can get the factory switches from jeepsareus on ebay.
if you're talking about the switches that look like ARB switches, you're looking for a "Carling" switch.
PM 'erickpl' or search his posts. He has a trick setup in his TJ using two switch panels and 6 Carling switches.
Yeah those switches look great, but I only have one set of lights, and no factory accessories, so the three stock switch holes are plenty for me, I just need to locate some switches that will drop into the existing holes.
