A system for control of electrical devices is provided. An adapter is provided having an electrical power interface for connecting to an electrical power supply, a switch to complete or break an electrical power circuit, a timer module operable to receive and maintain time information and timing instructions associated with criteria for completing or breaking the electrical power circuit, and a programming interface for receiving the time information and timing instructions from a programming module. In use, a user modifies the time information and/or one or more timing instructions via the programming module, connects the programming module to the adapter for communication of the modified time information and/or timing instructions and disconnects the programming module from the adapter, the adapter remaining operable to complete or break the electrical power circuit to which an electrical device is connected even after the disconnection of the programming module.
