These used to be really common parts into the late 80’s but since micro controllers have taken over, they are getting harder to find since everything is done in code now.
Try the search term ‘interlocking push button switches’, that might get you in the right direction. I don’t know exactly how the part numbering works, but I’m pretty sure you have to purchase the switches and mounting/linking hardware separate and then assemble them into the configuration you need. Check [this switch as an example and have a look at the data sheet for the different switch and linking options.](F2UOA01AAU C&K | Switches | DigiKey)
