I have a 5VDC 15A power supply that will be powering both an Arduino and 288 Addressable LEDs. How do I switch the circuit on and off? First I looked at relays. The only relays that I could find that support a 15A load are ones that use High Voltages around 250V. I think they had a minimum recommended load voltage of 12V. I also looked at mosfets, but I found that many would burn up if I put 15A of current through them.
I have also considered just using a switch, as everything is at the same voltage. In that case, I would need to make sure the switch I use can handle the 15 A of current. Hopefully a switch like that wouldn't be too bulky.
Basically, My load voltage is too low to use a relay, but I'm afraid the current is too high to use a mosfet or normal switch. How should I turn this thing on and off?
