SM5 switch panels - Scarlet O'Hara - 12-02-2019
Does anybody know if spare parts are available for the Lucas SM5 switch panel. I'm looking for a new spring contact with the two rollers as in photo, I think it's to do with the shunt for the dynamo switching the charge rate from summer to winter. Alternatively, are there any other lucas switches with similar parts that can cannibalize for parts?

I have new springs for the switches if you need them. ChrisC. (address, e-mail & tel.no. - back page A7CA mag under 2-seater Boattail Registrar)

Yes, this part switches from half to full charge if either the full charge ignition switch or the headlights are switched on. It shorts together F and D on the dynamo which are otherwise connected through a resistance.
