Funny this topic has came up again, a few weeks ago mine started leaking for the third time, i have replaced the switch twice in less than 2 years, NO MORE.
I went to Auto zone and bought a 12mm x 1.5pitch bolt, cut it just about 2 threads shorter than the exposed threads that were on the switch, used the crush washer that was on the switch, little high temp RTV and all is well.
I did let the gearbox fluid drain overnight and cleaned the switch hole threads with a Q tip and some carb cleaner, damn sure aint leaking now.
On the R100GS you have to pull the clutch in to start it any way so no big loss not having the switch, just no light for N.
On a side note just today as i was savoring the moment of defeating that oil leak and i discovered a new one starting, Pushrod tube seals, i looked all over the bike to see if it had made by AMF Harley Davidson but it doesnt, it just says BMW.
