Hi guys,
i'm planning to build a mcp with IOCards and i'm looking out for rotary switches. Do i use these for the knobs on the mcp? or do i use something else? I've been reading on lots of places to use a 1x12 rotary but i chanced upon a place that says to use a 3x4 as it has much simpler wiring. no need to connect pins. is this true? What would be the difference? can someone mind explaining the wiring to me? thanks.
