Slowly working through the wiring with this. One question i've got that I can't seem to find the answer for is whether USB connections actually need the power wires to be used.
Jimmying up a setup for switching the output from the tablet USB lead to another one that'll be fed to the centre console for use with the laptop. Figured there's be less chance of weird stuff going on if the laptop isn't just hooked into the USB hub.
Switch i've got half installed is a 2-pole, 2-way switch so has two input connections and two sets of two connections for the output. So thinking i'll have to either use a second switch to switch the power wires or just hook all three connections up to the power supply and hope it doesn't do anything weird having both permanently powered.
Kinda wish i'd thought of it before going crazy with the heat shrink
