Reverse polarity switch question

[Goldguy]

I purchased a 10amp 125vac switch for reversing polarity on my go kart. Is it appropriate for a 35.6 amp motor draw, on a 48v system?

Is this wiring diagram correct for a center off position http://www.instructables.com/files/orig/F2X/EWW5/F3HY3U9G/F2XEWW5F3HY3U9G.jpg

A 10 amp AC won't cut it, the diagrams is right though.

Thanks, What amp do I need to purchase?

My brain isn't working good enough to even attempt calculating this all out for you this morning :rolleyes3: but I think this link has all the diferent formulas you'd need to calculate your 110v.AC to 48v.DC amperage draw conversion:http://www.powerstream.com/Amps-Watts.htm
