Slightly off topic i know, but i thought this perhaps the best place to ask.

Does anyone know of a part which will allow high current switching without having to use a relay, they are so big and cumbersome.

I was looking at something similar to an opto-isolator, but they all seem to have a reasonably low switching voltage and current.

Or indeed any other suggestion to use a non mechanical switch.

I'm looking at using it for a vehicle application using the PIC.

Many thanks,
