Looking for a switch

[StevenD]

This is on the control board of a Breville Smart Oven. As you see, one of the contacts broke off one of the selector knobs. I am trying to find a replacement for the switch itself since the whole replacement board is always on backorder.

I have looked all over this thing with a magnifying lens, but the only identifying mark I see is a "B"...no other letters, numbers, or marks at all.

Thanks in advance!

The broken contact:

Sorry, mods, I now see that I should have posted this in the "Datasheets, Schematics, Manuals and Parts" section.
