I never use the electrical switch to disable buildings. I know that keeping every device powered is wasteful but I hate organizing the whole switch system because you need to make these switches well accessible and you need a very good base design to make it work properly. Instead, I just build a lot of power generators and batteries so that my base almost never runs out of energy with all devices running. Why not add the possibility to remote flip the switches and have a base room dedicated to all these switches? While being in that room, you can then flip any switch from a distance. Maybe even add a remote control (more expensive, some kind of 'wireless' research?) so that you can do it from anywhere in the base? I see a lot of more potential in 'wireless' research.
