Cool mechanic, but is the game supposed at "Emergency switch"? I reached it and moved all the way to the right until I fell off the platform, then the chain self-detached and I lost power falling in the void.

Unfortunately no, it's a bug due to janky physics. You're supposed always be connected to the engine from the start of the game, then you can't go far beyond the emergency box. True ending is to find the only way to power both the gear and the switch on the higher floor while still connected to the engine - you can check it out in the playthrough video on this page.
In any case, thanks a lot for playing!
