Finally got some time to examine the bad switch and discovered that the reason for the "failure" was due to the loss of the ball bearing that provided the detent action. The switch shaft rotates a few degrees, enough to move the contact from "Off" to "On", but there is no feedback that the switch has moved the required amount.

Fortunately, the missing bearing was located on the bench. Unfortunately, I dropped it in the radio on the 7th attempt to reinstall it and it got by my protective cover that had caught it after each of the previous attempts. After 30 minutes of searching the bowels of the chassis I cannot find it anywhere. I had pulled the switch from its mounting hole but it was still connected to its wires. Hopefully the missing bearing won't short something.....my hand still stings from repeatedly slapping my forehead.

Wish I could roll back the clock a few hours but retain the memory of what happened! I also wish I knew why the bearing dropped out of the switch in the first place. The retaining clip seems springy enough.

Anyone know what size that bearing was? 3/32", maybe? I'm going to visit my regional hardware store tomorrow.
