You will have to get the bezel off the front, if my 410 is anything to go by, as the switch itself lies behind the steel work that supports the wooden dash.
The bezel undoes the normal way. I made up a U shaped "undoer" which works well, out of a piece of scrap steel sheet. Picture attached. It is far better than a posh tool that I later bought in a weak moment
Once the bezel is off the switch should pop off the back quite easily but you would be wise to first remove the padding that lies below the dash. (On my car this is held by a number of self tapping screws, mostly self evident but there are two right at each end which are less obvious). This to give you reasonable access to the wiring to see and note what goes where.
The switch itself does of course have carry the whole of the switched load, which includes the cooling and heater fans, wipers, et al, which is really a bit much to ask of a Lucas design which dates back to well before the war. In short, it's really not up to the job that development has forced upon it. I have arranged that this considerable load is carried via a very heavy duty relay, in the hope that this will mean I have no further trouble from the switch. Might be something to consider.......
