The topic of a proper power switch comes up again and again and the options so far are quite limited (high amp car hifi breaker, connector loop, 60€ aps switch which is very out of stock). Now I asked a friend about it and he told me we could basically use a mosfet for switching. As far as I understand they can work just like a relay but are less bulky and way cheaper, if we find one that has the right specs for the job. Can anyone with more electrical knowledge chime in? I suppose there must be some reason that prevents them from being used?
