Headlight Switch Bad? Or Worse...

[BoxsterHtownTX]

Right high beam went out and the switch cannot turn the knob to Parking lights (stuck). Also when I pull the knob to turn the high beam it goes back inside. When I shake the switch it rattles like there's a broken piece inside. Used multimeter to measure voltage on headlight assembly connectors 2 (ground) and 4 (high beam) there's no voltage reading. Is this a broken switch that cleaning will not fix?

As it's near-identical to the switch in my Mercedes W124, the plastic breaks down inside and crumbles. I've had to replace a genuine MB switch on mine 6 years after last installing... a genuine MB switch.

Somewhere on the forum, is a picture of an old switch that was X/O and opened up. It is just pieces flopping around on the inside. There is a lot of German engineering going on inside that switch.
