I use mechanical relays to switch AC power for pumps and similar AC motor loads using DC signals from Arduinos and similar.
I have very very little experience with electrical engineering (I'm in the Lego mindset of I plug things in according to things I find online until they work), but is there something I should be using instead with 120V ~3-5 A loads?
