OK I'm having problems getting the switch from Morgan. Their part number is MDE1517. What gets on my goat is that it was fixed to the module with a connector and they've now decided to solder it. That makes replacement a right PITA.. 4/4 parts book here.
http://mog2904.free.fr/morgan-traditional-parts-book/morgan-traditional-parts-book-2006.pdfI rang Lorlin and it would seem this is the part.
It's a Lorlin part CK1027.
They are £1.50 each. I've ordered two. I had to describe fully the switch to Lorlin's technical debt so they could supply the correct part.
I will advise how I get on when I try to install it..
