Headlight Switch Blows Fuse

I have a 74 914 2.0. I went to drive the car the other night and when I pulled the headlight switch out to turn the lights on, it blew a fuse under the dash. I replaced the fuse twice and each time the fuse blew immediately upon pulling the light switch out. I opened the headlights manually and they worked fine. All instrument lights were lit except for the console guages. I pulled the headlight switch and did not visually find a problem. Could a faulty headlight switch be the cause of blown fuses or could it be caused by something else. Any help is appreciated.

yes, or 30 year old wiring getting a bit to much resistance, bad ground could probably do that too

Have any body work done lately? Anyone remove the rear bumper, say? Someone putting the wires for the license plate lights on backwards caused that sort of problem for me. Since the console lights are out, check for shorts on that circuit.
