Is there a special name for this part?
Have been asked to add an external DC power supply jack to a normally battery powered item, but still retain the battery powered possibility. To avoid issues, i'd like to use a jack that disconnects the internal batteries when the plug is inserted instead of having a switch or something. I know they exist but searching hasn't got me too far (so many items to filter through) finding anything that specifically states that it works in that way. Hoping that somewhere like Jaycar stocks them so i can just pick one up easily.
