Abstract
A plug ejector for ejecting an electrical plug from an electrical power supply socket comprises an electronic device having a controller that monitors and senses electrical power supply characteristics and a solenoid, which operates an ejector member to separate the plug from the socket when predetermined sequence in rapid changes in electrical power supply characteristics are sensed. The plug ejector can be incorporated into an electrical appliance or extension power cord electrical plug, which plugs into and is ejected from a conventional power supply socket. It can also be mounted in an adaptor, which receives an appliance or extension cord plug and ejects the adapter from a conventional power supply socket. It can also be incorporated into a module, which is semi-permanently plugged into a conventional power supply socket or incorporated into a wall or other power supply socket. Upon rapid cycling of the appliance's On/Off switch, the solenoid projects the ejector to eject the plug and thus free the appliance or extension power cord from the power supply socket. The plug ejector may incorporate a GFCI protector.
