I have two sources of power supplies one coming from my main wall socket 2nd is coming from my PMA now I have two issues if you kindly answer my following questions?
1. I want to use either the main wall socket or power from PMA at a time what type of switch I should use and how to wire it?
I do not want to use a three-stage selector because I do not want to break continuity when shifting the power source from 1 to 2
