Abstract
A power adapter has a solenoid actuated retaining latch controlled by an electronic circuit that detects the presence or absence of AC mains voltage. When the assembled AC-DC adapter and plug assembly are removed from the wall, the latch detects removal and unlocks the plug assembly for easy removal without undue force required by the user. The circuit is designed for minimal power consumption, and the solenoid only consumes power when it is engaging or disengaging the latch.
