/*

  Scope and purpose:
  en power on knapp som styre ingangsrele te 24v rail
  en Loudness knapp som styre et rele som skrur 2 tweetera på
  en toggle switch som e på et aent kort men når den e High 3.3v så ska an skru av et rele og på et anna og motsatt

  må tenka energieffektivt her og
  kan ikkje ha masse rele så trekke strøm når du e på batteri
