This is a push to start pull to stop switch with 2NO contacts.
This is a normally open switch when pushed in, it has 1 contact that closes when knob is pulled out to the start position (it stays in this position until it's pressed again), the second contact closes momentarily when knob is pulled out further (it will not stay in this position and is spring return to the start position).
