** Probably not, Glenn. Relay contacts typically have less V-drop than
a Si junction. Also, relays are more likely to function in RF
environments. Sometimes, high-tech is not without problems. An example
is anti-lock brakes. On a test-track, ABS is clearly the best, however,
autos equipped with ABS have a higher accident rate than those autos
without ABS.
