The question is as simple as it sounds. What action or sequence of actions do you take to remove detachable electronic contacts from detachable electronic contact receptacles?
Personally, I find that it helps to hold the plug with my index finger, place my thumb on the edge of the connection point, and flick it out of the socket. This works on virtually all connections, including ones with very little contact area and nothing to hold on to, as well as being easily executable with one hand.
How do you unplug things?
