I'm designing a circuit that would switch between stereo-jack inputs. Source audio would be plugged into one end, and on the other two ends, two different audio outputs. I want to be able to switch between one of the two outputs.
Physically, I know how to do this, it is very simple using a double throw switch.
However, if I want to do this digitally, using a micro-controller board to control the switching, what type of component would I use?
I know that the digital equivalent of a SPST is an NPN-transistor. What is the digital equivalent of DT switch? Any support multiple poles?
A poor diagram of what I want to do.
