RE: transistors instead of relays

[Luis Marques <marques@raytheon.com>]

"Solid state relays" is nothing but a fancy term for a large
transistor.  Ever wonder how they manage to switch without any moving
parts?  Although newer transistors have a very low on resistance, it's
still there, and more likely than not, any "solid state relay" that you
find for automotive use won't be state of the art, but a few years
behind the curve.  IMHO, unless you can find a solid state transistor
with an on resistance in the order of just a few miliohms, you are
better off using good quality relays.
