Hey all, I really wanted some kind of box on my desk that I could use to quickly switch between my headset, headphones and amplifier so I could select my audio output without having to rummage around behind my computer plugging things in. So I had this idea to have a box with one female "input" socket and three female "output" socket all for 3.5mm jacks. A rotary switch in the middle could be used to select which output was activated. At first I thought "simples" I can just use a 3P3T switch and wire it all together. Most basic solution. TBH I don't know how 3p3t rotary switches work, so I don't know if this is possible. Then I thought it would be cool to have indicator LEDs to show which output was selected. I think maybe this requires some transistors but I have never used a transistor in my life and don't really know how it works. So here I have made a (draft) circuit design using a battery to provide a voltage to the gates of the transistors, indicator LEDs not included. I think in reality it will be more complex because it would be in stereo. Is this a good solution? What kind of transistors would I need? BJT/Mosfet/pnp/npn?
