An electrical timer having pre-set options, electronically set via e-prom and microprocessor or other solid-state circuitry, for the activation of an electrical receptacle, with ground-fault circuit protection, contained within the timer housing. This timer is novel and differs from others, as it is designed for user-activation and instantaneous energizalion of said receptacle, based upon immediate need and for fixed and pre-set durations, independent of time-of-day, chronological, calendar-based, or other pre-scheduled means, using simplified selections and modalities, and providing ongoing visual status of timer activity. The timer also has a manual reset (off) function. According to a further aspect, switching-times mechanism is co-located within the timer housing, which includes a suitable electrical plug, an electrical receptacle, an electrical switch operable with the timer, and shock protection via ground-fault circuit interruption circuitry.
