I've read several posts where relay failure caused a considerable amount of
grief. In particular, the relay contacts welding closed due to current and
arching.
 
Has anyone considered or actually wired up their circuits so that the relay
contact simply supplies power to the gate of a HEXFET which requires a minuscule
current, and then have the HEXFET trigger the load at the load current?
 
The relay could be any desired arrangement, SPST, SPDT, 4PDT, etc. Each pole is
connected to a HEXFET gate and the remaining legs on the HEXFET go to ground and
the load.

I am asking if anyone has considered it or done it. I am not suggesting doing it.
