   A couple of original switches have stopped working in my MGBs due to
the contacts wearing away. Replacement switches have not been as robust
as the originals and have been hot to the touch when used for headlamp
switches w/o relays.   I disassembled a non-working original and found
that 4-40 brass machine screws will substitute for the original contacts
quite well.  Since then, two switches that I have refurbished that way
are cooler to the touch than the new switches. Before discarding old
switches, one might want to open them and see if they can be serviced.
There is a patina to 30-year-old plastic that is lacking in new switches.
