I made a lag switch with a push on/off switch. The only issue is I'm not entirly sure when it's on and when it's off. To fix this, I wanted to add an led to let me know when the switch is set to on. What would be the best way to do this and what would be the best power supply? I was thinking of just hooking an led and batery (maybe a AAA) in series to the switch, and add a ressistor if needed, but I was thinking that might mess up my Internet connection in some way since one of wires of the Ethernet cables would be on the same switch, any solutions?
P.s. Kinda a noob with electronics, so add as much detail as possible (like what kind of ressistor, if any, I need for the power supply you sugest)
