Nailed it in ONE, good sir! Thank you very much!! The switch was indeed gummed up, but cleaned and lubed with silicone lube that dries non-sticky now.
The trick NOW is getting the bracket to fit the support piece. It's located by a tang and a screw to lock in the adjustment. Unfortunately, those items are about 1/8" too close together and both will not go into their respective holes at the same time. Looks like a job for Mr. Dremel!
