The switch is a Lucas 30390 Switch 119a. They are obsolete now and sometimes turn up as NOS, (New Old Stock). The cheapest place I can see one is PureFord.co.uk for £79.99. It apparently fits an old Ford Transit!
HoEs is a new one, so might last longer.
If I see them at auto jumbles, I buy them if they are less than £50.00. A friend's car had my last spare.
(Auto cancelling is over rated anyway - just turn them off!)
