Left-handed 3-pole disconnect switches? SparkyGuy 01-24-08

I need a 3-pole safety disconnect switch rated at 208V / 60A, unfused. I can
find one at any of several equipment suppliers, except for this requirement:
I need the operating handle to be on the left side of the cabinet.

The location of the equipment is such that a right-handed switch will require
either locating the switch in an inconvenient location or moving the
equipment.

Does anyone make disconnects with a left-oriented operating handle?

Won't the unit turn upside down ? Some I've seen in the past do this as
the switch handle still rotates the same way to connect/disconnect.

The kind I'm familiar with are knife switches with a handle on the side that
pushes up and down (not rotates). Such as:

Can you give me a URL to a switch you're referring to? Sounds like a possible
solution...

(I should have mentioned that this is for N. America...)

Ideally, you would require an actuating handle which is independant of left or
right handed operation.

Have you considered using a panel mount non-lockable handle mechanism such as
this http://www.acicontrols.com/catalog/product_detail.cfm?ID=203

This can be mounted to a 3 pole switch such as backpanel XA063BY
