Abstract
An electric wall switch has an outer casing on which incoming hot and cold line connectors and outgoing hot and cold load connectors are provided. A ground fault circuit interrupter is connected within the casing between the incoming and outgoing connectors for detecting ground faults and for opening the circuit between the incoming and outgoing connectors on detection of a ground fault. At least one of the outgoing hot load connectors is connected to the ground fault circuit interrupter via a switch for controlling powering of any device connected to that connector.
