I have a garbage condition 1433. It has few good switches with very low and stable contact resistance. CM, I can easily donate a switch.
Now we can fit it with just 4 binding posts to limit the need for expensive low emf posts.
This decade has 11 positions and each of them can be wired individually with a different resistor going directly to common. This can give us these values from the same box:
10ohm, 20, 100, 200, 1k, 2k, 10k, 20k, 100k, 200k, and 1M.
This sequence covers full range on most meters and also allows us to check linearity of a meter, by having known non full scale values.
I also have some resistors from 1433. Tempco of these resistors is not the best, but not horrible also.
Another thing to consider is that 1433 switch has 4 individual wiper blades. If we can separate them as 2 and 2 we can bring 4 terminal kelvin connections right to the contact, eliminating contact resistance at all.
This would be fairly compact and light traveling 4 terminal resistance standard covering much of a useful range.
Is this something you would want to try? I have a milling machine and can help with making precision holes in a casing.
