| Oct 11, 2020 at 11:50 | comment | added | Caius Jard | That's a good point, I suppose they would be better for soft start than relays! Though I suppose it would then invert my question; if MOSFETs can handle the currents involved, why use relays? Is it because they can switch ground well/high current but not positive voltages? | |
