MikeLemon:
and for the third time I just want to connect a mechanical switch to close and open the circuit from the mosfet array and thats it, how hard is it to understand?
Apparently about as hard as it is to answer questions posed to you. Answers to which are key to how you may be able to electronically switch your 50+ A load, which as you should have figured by now is not trivial.
Still wondering where the Arduino is in this whole thing.
