How do I remove theses buttons/switches 65 Valiant?

After reading the posts it seems the methods described leave the solution unclear.
Your wiper switch should have an allen socket setscrew on the side of the knob itself. The headlight knob comes out with the stem attached after you press the button on the side of the switch body ( the rusty one on the switch in the photo above). You may have to push it in and pull it out a few times with the button depressed as they sometimes stick after 50, or so, years.
