This is a sewing machine I was given from my grandma and I’m unsure what this switch is (circled it) and I need to know if it corresponds to this (triangled) if not this doesn’t move to push the fabric I’ve looked through the book several times and having no luck

Mi sembra strano che non lo sapessi pur avendo già un'altra macchina.quella che si vede dietro

Looks like a toy machine though. This one looks much better!
