Alibaba supply just the type of "spring return rotary switch" you are looking for, but only in a minimum order quantity of 1000 pieces!
I wonder if anyone in the trade who bulk buys the switches goes on to retail them in smaller quantities?

Actually I was able to source a momentary rotary switch from a mechanics shop. It fit the case and everything works 😀.
So last three days have been mostly spent building the damn thing.
I went with the front firing setup and I it sounds very good, there are no rattles from the old case, the speakers are also not sealed off, but it still sounds good, so I will probably keep it that way.
Most of the time was spent on getting the volume button to work, it uses cogs and different layers of mountings to get the volume indicator spinning.
There is still a lot of stuff to do: Correct knobs should arrive in a few weeks, I need to secure the mounts inside a little better, front panel screw holes need to be filled, back panel needs a inner cover to close it up.
Lastly, although it sound very good, there is a lack of bass. I found from Visaton a smaller subwoofer, KT 100 V. There is also a space on the right side, when looking from back, for the subwoofer, there is also a hole in the middle there where it could stick out. What do you think here, should I go for it? How would I deal with the crossovers when I have stereo speakers and only one bass?

Your lack of bass would be greatly alleviated if you seal the speakers off at the front (you could devise something using closed cell foam), and add a sturdy sealed back.
If you wanted a subwoofer, you would need a 2.1 bluetooth amplifier board which incorporates a stereo amp for the two satellite speakers and a mono amp for the sub - and not a passive crossover.
However, you've already bought a stereo amplifier version so you are committed!

These are related. Any hole in the cabinet cancels bass. The original was weak below 250Hz for this reason (the carefully sized back holes *may* have added a resonance). Unless your "subwoofer" has its own box, it will have the same problem.
The original had to be ventilated for the tubes. Your new stuff will run so much cooler you may be able to use a solid plywood back with felt sealing.

Sorry, wasn't able to answer sooner, busy week. I will seal the back and any larger holes I find but I'm afraid the bass will not improve much, will see. If it works I will save a lot of time and money on the project. I have listened to it for some time now and compared it to my regular home setup and it actually is not that much worse and my home setup has decent towers and subwoofer and all.
My thinking was to take bass from 1 channel, the amp is strong enough to support it. I had the plan to put low pass crossover between, lets say, right channel and add the bass speaker from that. There is room in the back for a small MDF compartment for the bass speaker so I would not be out in the open. I also found a "stereo subwoofer crossover" Looking for a Subwoofer Crossover 130 Hz? - SoundImports but I'm not sure on how it works because it has 4 outputs and I need only 3.

I'm pretty sure that sealing the speakers in the cabinet will improve the bass response.
I don't see any advantage in adding a subwoofer unless the enclosure in which it is housed is optimised to the driver's parameters.
Anyway, the "dual voice coil" subwoofer crossover to which you linked is inappropriate to the task.

You need to totally seal the cabinet.
Furthermore, there can be no way that the sound emerging from the rear of the two loudspeakers can come round and cancel the sound emerging from the front. That would produce bass cancellation.
I say this because your method of mounting the speakers makes me think that the speakers are not sealed up against the front of the radio cabinet.
