Creek Integrated Amp 5250SE -various Versions for Input Selector Switches

By order of an input selector switch for a remote controlled version the supplier provides for a friend of me a normal alps input selector switch as to see about
instead of the wanted motor version.
Obviously the rc controlled switch isn't longer available in Germany.

Follow questions rises up:

1) who knows the alps order code of those motor controlled rotary switch from alps?
2) what must I do for dismanteling of that switch after resolder from PCB?
3) are there different versions of the input selector switch and input selector PCB from the rc controlled 5250SE devicves?

Thank you very much for your help.
