I bought an equivalent part from Mouser or Digikey (cant remember) to
replace all the switches in my 303.

It was almost identical except the head was slightly larger and the switch
caps didnt fit. I just used a nail file to trim down them a little. It was a
bit of a pain in the ass, but it worked out in the end.

My recommendation: Measure your existing part very carefully and check the
part specs before you order them. The only dimension that really matters is
the head size though. The pinout and height are pretty standard.
