Abstract
A plug-and-socket arrangement connects an appliance to a mains-powered battery charger/power supply. To avoid unwanted power consumption when the appliance is disconnected from the charger/power supply, the plug-and-socket arrangement disconnects the mains power from the battery charger/power supply when the appliance plug is disconnected from the appliance socket.
