2000 CR-V intermittent starting problem

I have a 2000 CR-V EX automatic in the US. Over the past couple of weeks it has had intermittent starting problems.
I turn the key and all the usual lights come on, but the engine does not
turn over - no starter noises and no other noises.
I try several more times over the space of about a minute, and eventually the engine starts fine.
Sometimes, I hold the key all the way over in the start position and jiggle the key vigorously, and the engine starts.
Another time, I took the key out, turned it over, reinserted it, and the engine started.
Most of the time, the engine had been running recently. It had been off for about a minute, to maybe 30 minutes, when the engine would not start.
One time, the engine had been off overnight, and was cold, and it did not start.
This happens about 10% of the time I try to start the car.
I checked the battery with a simple voltmeter, and it was around 13 to 14 volts.
There were several Honda recalls regrading faulty ignition switches, where worn parts of the switch would cause a running engine to stop running - not quite like my problem. I called Honda, and they said that none of the recalls applied to my car.
Anybody have any ideas?
I bought a starter switch, which attaches to the back of the lock cylinder assembly, but it looks like a stinker to replace. Besides, since the problem is intermittent, I do not really know where the problem actually is.
Thanks for any ideas!

1. replace ignition switch. 2. remove all the heavy junk off your key ring. 3. in future, ensure the key is returned completely to "run" once you're done with "start".

Thanks!
By "ignition switch" I assume we are talking about the thing that attaches on the back of the lock cylinder assembly, and not the part that the key actually goes into.
I do have a lot of stuff that hangs off of the key ring. That is gone now.
Looks like an afternoon spent under the dashboard...

Lube the ignition lock with LockEase (messy graphite) spray. Do all four of your other locks while you're at it. You'll think you got a new car overnight. Just because there's no recall for your V, that doesn't mean the switch isn't bad, but I suspect your starter armature too.

You'll also learn about valve adjustments if you hang around there . .
