How do I use the power switch at the beginning of the game?

[GrenadesAndHamm]

It's unlocked failry early. I've tried to find answers on here and in videos and can't find one.

How is it used? For example, if I hook it up to the massage table, will they turn it no before they use it, and off after, thus saving power?

Thanks for the help.

Machines dont consume power when inactive like Table with no dupe on it or Water pump when pipes are full.
Dupes wont flip switches without an order but if wires placed thoughtfully you can have switches inside base (or closer to base) so dupes disable machinery without need to go for it directly. Or to disable set of machines at once.

I see, thanks.
