Number one is a heater switch for a single speed fan.

Number two might be a wiper switch or headlight switch. The wiper switch would have three positions if you count 'of as one of the positions. The wiper switch pulls out; I can't remember if the headlight switch turns or pulls.

Number three is without a doubt a heater fan speed switch. Just go to evil bay and look for Mercedes 111 heater switches. If you don't see one then check on the 'sold' items. These come up all the time.

Number four is not a Mercedes switch since it has the screw down poles and not the plug in. Porsche used a few of these, but their switches usually had blades that the wires plugged into. Well, put it this way: I would be surprised if number four were a Mercedes switch.

And I don't know that logo but I see it a lot. If anyone knows the name of this company I would like to know it as well.
