I purchased a desk light at Home Depot. It has an amazing featu it
is switched by touching its base. It does not have a mechanical

Interesting. Those lamp switching devices have been made since the
50's. Used a vacuum tube, then. You do realize this is just one more
electrical device that is always turned on, even though the light is
off.
