this is the switch in the "On" position - hard to see due to lighting



If the contacts are touching when the key is out check to see if the light contact spring(s) have gotten bent. It happens. More often than not it is the heavy brass contact that is bent; open, or close, the gap (between the light spring contact and the heavy brass one) by carefully bending it. It's definitely a trial-and-error operation.

Very visual and understandable - thanks again, Lew.
