Rotary 230v source select switch with 4 inputs..is this possible to buy?

[fuss]

I was wondering if there is a 230v rotary switch that has 4 inputs as the maximum I can find is 3, Shore Power, Generator and Inverter. I would like to have an extra one.
I'm sure this exists somewhere but I cannot find one, 3 seems to be the maximum.

what you need is a two pole ( live & neutral ) break-before-make ( to ensure you never join two sources together ) three-way (or more) switch rated above the maximum amperage that you might draw and with suitable fuses/breakers in each circuit.

These will do the trick:

edit: sorry - just realised you asked for four poles, I'm not sure Ive seen one of those either but its easy to achieve more inputs by cascading more than one switch though I cant think of why you might need more than three poles.

edit 2: okay there is a 4 pole version but its a special order type but can be labelled to suit your application so would look the part too: http://www.newmarpower.com/AC_Source_Switches_Panels/AC_Source_Switches_Panels.html
