Even after rebuilding each Delco switch (One for the Master and one for the Standard) the dash light switch is still a bit touchy to work. Dash light switch button at the top of the casting.   Switch contact (long tab) Needs to be well cleaned for good contact. Burnt ignition switch contacts.    Replaced contacts and then I had to make some epoxy to fill the charred recessed sections of the Bakelite plate.
