Hi
I'm trying to build a Kelvin-Varley Divider network to have precision voltage dividers. Can I realistically use Analog Switches/Muxes to tap the resistors at each decade. I know that when they make precision KVDs, they have to use very low resistance rotary switches.
Does anyone know how to calculate the acceptable maximum ON/contact resistance for the switches?
I'm most likely going to be using the 10K, 2K, 400R, 80R 16R decades.
