Unhappy Clutch safety switch leaving starting circuit open with lever pulled in

I posted about this on another thread a couple of days ago, and thought the problem might be burned or partially burned contacts in the starter button. That does not seem to be the case after further experimenting.

Until a week or ten days ago the starter circuit safety switches all worked as they are supposed to. Then one time it would not start in 1st gear with the clutch pulled in. Shifted into neutral and still wouldn`t start with clutch pulled in, but would with clutch released. I`m confused. 19 times out of 20 now, it won`t start with the clutch lever pulled in, whether in neutral or in gear.

Did some testing of it after work Friday. The engine will start every time in neutral with the clutch lever released.
Shut it off, pull the lever in and hit the start button--nothing--nada--no go.
Release lever and hit start, it starts.

Then, just once in a while, maybe 1 time in 20, it will crank over and start with the clutch lever pulled in.
Shut it off, try again. No Go.
Lever out and it starts again.

This can be a dangerous situation if I stall when moving off from a traffic light. It doesn`t happen often, but now I worry about it if there is a lot of traffic behind me. After stalling it takes a second or two to shift into neutral, release clutch, start engine, shift into gear and move off again. On Friday I stalled on the way home, then got flustered and stalled twice more before I cleared that intersection.

The connector to the switch seems tight.
Guess I`ll have to examine it closer, maybe take it off and see if something is loose or broken inside.

the switch might not be making contact when the lever is engaged

Thanks slim. I`ll check that if/when it acts up again.

Just came in after playing with the starter and clutch again, and it now starts immediately almost every time with the clutch pulled in, or out.

Notice I said it starts ALMOST every time.
Still a couple of times when it wouldn`t turn over. Various combinations of jiggling the key, wiggling the engine run/off switch a bit, starting it with the clutch out, then try again and it would start with the clutch pulled in.
What gives?

Pulled the connector off and saw a bit of dry corrosion on those tiny little contacts, so sprayed with electrical cleaner, worked the connector in and out a few times for some mechanical cleaning, then pushed some dielectric grease in.

Seems to be working properly again now.
I`ll see how it works tomorrow and the rest of the week.
