Steve: that looks quite similar to the one on my 77 coach. With the engine shut down and the Jake dash switch on you can gently run a small screwdriver or something similar between the rod end and the switch and that should trigger the microswitch if it is functional (or not if it isn't).
If the switch checks out then you will need to do the buffer switch adjustment by turning the threaded rod into the housing 1/8th of a turn at a time until it starts functioning. If the switch is dead, then following its replacement you have to do the whole adjustment process as described in the manual. None of this is difficult (the hardest part is keeping your body parts out of the rotating fan while doing the initial adjustment to eliminate the "rolling idle" mentioned in the manual - though in my case fear of dismemberment was incentive enough to take it slow). Just get the new switch initially threaded into the governor housing, start the engine and work slowly in. If you see blood you dun sumpen rong. It really is a pretty straightforward job.
