Abstract

An electrical power supply continuity module for an electrical power supply timer operable with an electrical outlet device, the electrical power supply timer having at least one scheduled switch off period for stopping electrical power supply through the electrical outlet device, the electrical power supply continuity module operable with a sensor for sensing electrical power supplied to an electrical apparatus by the electrical outlet device, wherein the electrical power supply continuity module is operable to receive from the sensor an indication of electrical power supply to an electrical apparatus at a chosen time before a scheduled switch off period of the electrical power supply timer, the continuity module operable to override at least part of the scheduled switch off period such that electrical power is supplied during at least part of the scheduled switch off period.
