1) Ignition: after removing the cylinder, unplug the wire plug and disconnect wires from the back. Push the switch forward, and turn 1/8 turn CCW (Kind of like the taillight bulbs are removed)
2) Headlight switch: Pull out on the knob, depress the button on the bottom of the switch, and pull knob out of the switch. Insert special tool (or LARGE phillips screwdriver into cross-shaped hole and unscrew, holding the switch in place in the back. (about 6-8 turns)
3) Wiper switch: remove knob by loosening allen screw at base, push and turn (similar to #1)
Hope this helps. After several years, these are very hard to get out (the ignition especially).
