Main Panel Switch needed or 1997 40 mid cabin express - Salty0ne - 03-28-2025

Hey group I'm looking for some help sourcing an original replacement or a suitable alternative. 

1997 Tiara 40 mid cabin express cruiser with the inverter option. 

Main panel A/C section has a 3 pole 4 position selector switch made by AMP Tech LLC Tiara Part#3291230
The selector switch options are
1) 120v Shore 
2) 240v Shore
3) Generator
4) Inverter

Tiara no longer carries the part and I have not had any success reaching the original manufacturer for a suitable replacement. 
The selector switch is a rotary switch mounted on a circuit board with 15 wires connected to it. I have traced and labeled all the wires but am unsure how I might be able to successfully connect everything to a cam style rotary switch. I have found something on Grainger.com but am concerned it may not accept all the needed connections.

Thanks for any assistance!
