what did you do with your fazer today ?

[unfazed]

Good fix Unfazed.  :thumbup

IIRC someone else had concluded the only way to get at a troublesome sidestand switch was to take the engine out!

I avoid using silicone greases on switches. It's OK on connectors which are forced together and displace the grease, but switches operate at much lower contact pressures.
If there is any arcing it can cause the grease to overheat: with carbon based compounds you get soot and CO2 which won't stop conduction, with silicone the products of overheating can include silica which will stop the contacts touching.

Yes it is generally thought the engine out at worst or the sump off at best is required to remove the side stand switch of the Fazer600. The lower bolt is accessible but the head of the top one is not, however the rear of the top bolt is accessible with the sprocket cover off.
I used a drill and sharp HSS bits to spin the bolt out from the rear. The problem was how to get it back in. :oops :lol

I drilled out the threads of the upper hole and super glued 2 washers and the nylock nut to the switch and was able to get the bolt from the top to screw into the nut before the superglue gave way. Then with a ground down (to get it to fit in the confined space) deep 8 mm ring spanner was able to hold the nut when doing the final tightening. I took photographs of some of the work. Now one bolt has the head at the top and the other has the head at the bottom.
A much better option than trying  to remove the downpipes and remove the sump or engine.
I must post a "How to fix the side stand switch" in the downloads, had it all apart, fixed and back together in 2.5 hours. Trying to find the 1200 wet and dry and stainless bolts, nylock nut and washers took me about half an hour.  :rolleyes The reason I used the Permatex dielectric grease is that it can withstand the high voltage arcing around the ignition coils. The contacts in the side stand switch are the sliding type and have a good strong spring. This gives good pressure and will displace the grease unlike contacts on relays and the like.
