US 2011/0031819 A1 · Electrical timer apparatus and a system for disconnecting electrical power

Abstract

An apparatus and system disconnects electrical power from an electrical power outlet. Specifically, the apparatus and system disconnects electrical power, such as AC power, from an electrical receptacle and a timer when the timer has expired. More specifically, the apparatus and system for disconnecting electrical power has a plurality of switches to engage a timer circuit. A first switch either engages the timer circuit or bypasses the timer circuit. Upon engaging the timer circuit, a second switch is engaged to supply power to the timer circuit for the duration of a timer. A third switch allows a user to select various timer values to set the duration of the timer. One or more indicators informs a user whether the bypass circuit is engaged or whether the timer circuit is engaged.

Dependent claims

An electrical timer apparatus comprising:

a connector to engage AC power from an AC power source;
a female electrical receptacle for engaging a male electrical plug;
a timer circuit comprising a timer selector for selecting a timed interval and a momentary switch for completing the timer circuit, wherein the timer circuit provides electrical power to the female electrical receptacle and to the timer circuit when the momentary switch is engaged and further wherein the timer circuit disconnects electrical power from the female electrical receptacle and the timer circuit when the timed interval elapses;
a bypass circuit for providing electrical power to the female electrical receptacle when the bypass circuit is completed with the AC power;
and
a switch to select either the timer circuit or the bypass circuit.
