I want to make a switchable resistance box, and rotary switches are nice, but I want to practice on analog switch IC's and digital, and they are cheaper than the rotary switches, and I could even and use an MCU and add a display and program the resistance that way. At least for the higher ranges right?
What sort of analog switches would be good enough to not matter in a resistance box? Or is that a bad idea if you really still want the precision?
Thanks to SamR I'm making an order list from Tayda, so what % resistors fo people usually use ? I can always replace the resistors later with better ones, I'll at least get 1% resistors.
