Hello!
So i got four of these:
https://www.don-audio.com/Elma-Rotary-switch-Type-06
And i want to make them into 1k log switches. They are only 12pos and are going to be used in a summing mixer, so i was thinking to have 2db attenuation pr step ? Seems reasonable? What resistor values should be used? And is this what youd call a series attenuator?
Over to the building process; ive been trying to read up on the theory, but i get confused. Resistors are soldered between the discrete and common terminal? Where is the input and output of the switch, and where do i connect ground?
Also, i once got some resistors that were really small in size, but i believe still 1/4w. What are these called, what search criteria do i input to find them in mousers inventory?
Thanks for any help,
Magnus
