I have my control panel and most of my components, just waiting on my SSR's from China. My design has my control panel plugging into my 60A disconnect box using a 240V 50A 4 prong plug. I also have the breaker for an power on/off switch. However, I've been wanting a MAIN power switch on my control panel but I don't believe they make a 50-60A 220V switch. Just curious to what some of you are doing?

I was thinking of using two 30A 220V light switches to control the 110 side L1, and the L2 coming in the control panel.

Automation direct sells them up to 600V

Similar type I use made by A-B.

I picked up a Square D 30A 300V relay. Apply 120 to the coil to close the switch, and it can deliver 30A @ 300V on 2 poles. Looks like this:

Yea, your best bet is a 120v capable switch and a contactor just like above. I've got an E-Stop switch wired like that and its nice to have that protection.
 
I'd suggest going to a local electrical supply shop and they should be able to get you what you need. They them you need a 'Normally Open Definite Purpose Contactor' that can handle 50A 250V on 2 poles, with a 120VAC coil voltage (or whatever type of voltage you plan to have available to actuate the coil) I think it would be easier to mount than a switch that could handle that, and you get the satisfying 'clunk' when you actuate it :)

EDIT: The one I purchased above cost me $25 at a local supply shop, though I see them selling for $40-$75 online.
