I finally found my tube of Permatex dielectric grease. I believe it would be a capital idea to use it on the new switch's terminals to protect against corrosion and ward off another switch failure. Corrosion on electrical contacts is a frequent cause of component failure.
This afternoon I proudly showed my collection of tools to a couple girlfriends, and they just shook their heads. They couldn't even appreciate the beauty of my gorgeous new torque wrench! They made japes at my expense. However, when something goes haywire with their rides, I'm the first person they call for advice. Different strokes.
