    What does the below do.
    Is this also an SPCO.
    I am a little bit confused I would google it first but I was unable to find much info

    All I want to know is can I use this to switch between 2 power sources?

    Thanks

    I would guess that SPNO would stand for Single Pole Normally Open. I don't have an explanation of SPCO.

    I think a type C relay is double throw. You can tell with a meter and a voltage source.

    NO normally open
    NC normally closed

    For every acronym, in any language, I run across, I type "XXX acronym" in the Google's text box .

    Up to now, I always got a result. Helpful.
