i thnik you got me on that one unsullied
if switch is on, caps still get charged, if switch is off, main board gets it's caps charged while brain board dosent get power.
ok so most people here gave up on the switch, but is that because you didn't like the reliability?
i just figured that leaving the main board powered for a little while whilst you go marshal a 10 min heat wouldent be so bad.
fets are pretty safe without a signal!
