I think these are called Carling style switches. I just moved a bunch from my lower panel to the ceiling area. I am pretty happy with the relocation. I do however need to redo my home made bracket mount because I just saw I am missing the beer switch... Huge oversight.
It is a standard shelf it product then I made a little bracket to place all the Carling switches in with the plastic switch holders. Turned out nice so I powder coated it black.
There is an ARB distributor with an eBay page that sells all the switches and plastic clip housings then you just have to figure where to put them. In my case I ran out of room down below so they had to go up top.
