High Current DC Switches?

[Demosthenes]

I want to hook up a 12v cell up in series with my 36V pack but put a DPDT throw switch in with it so I can switch between the two voltages at will. I've figured out how to wire it up and I have everything I need except a switch. Does anybody know where I can find a DC DPDT switch that will handle the current from my 35A controller? The most I've found is a 21A switch at 14VDC. Would this be the kind of thing an automotive supplier would have?

you need 35 amps total, but you can gang switches to handle more current. 2 sides of a 20A DPDT switch will handle 40A total.

you can do what you're wanting with a single TPDT switch. you just need it to have a Center off position.
