As an illustrative example of some design tradeoffs in power connector selection, consider the adjacent picture. A commonly seen coaxial power connector is usually set up so that power is fed "from" the female plug on the right "into" the male jack on the left (which is typically a part of the electronic device accepting the power). Although the plug is female, with a partially recessed center contact, it is still possible for casual accidental contact with a metallic object to short-circuit the power source. Depending on the design of the power adapter, it may react to a short circuit by shutting down temporarily, or instead by blowing out an internal safety fuse.
