meabh, I've been searching my files / notes and found this...
The switches are made by E.A.O the UK distributor was Mouser UK but the website was not very user friendly and even filtering by automotive switches gave over 26,000 results to search through.
Eventually I traced them to the E.A.O Series 61 but even they are complex with different part nrs for bezel, switch type, mounting, legend, illumination, actuation block
This part catalogue lists them by Farnell (another distributor) shown on page 434, 435 etc
