A resettable switching apparatus, useful in a GFCI receptacle, has an auto-monitoring circuit for automatically testing various functions and structures of the device. The auto-monitoring circuit initiates an auto-monitoring routine which, among other things, establishes a test fault situation on either the positive or negative half-wave of the power cycle and determines whether the detection mechanisms within the device appropriately detect the test fault and whether the device would trip in the event of an actual fault. Additional functionality of the auto-monitoring circuit permits automatic verification that the device is properly wired, that is, not miswired, and determines whether the device has reached the end of its useful life.

This invention discloses a ground fault circuit interrupter capable of detecting its end of life, and is characterized by: a pair of flexible metal sheets connected to the power output end are added on the circuit board of the interrupter, and there is a pair of moving contacts on the metal sheets; there are two pairs of fixed contacts on the power output conductors; the two pairs of fixed contacts on the power output conductors respectively correspond to the moving contacts on the power input metal sheets and the moving contacts on flexible metal sheets, thus forming two groups and four pairs of switches. There is also a tripping apparatus on the circuit board, which can release/trip the interrupter, thus cutting off the power output of the interrupter. An end of life detection circuit has also been added to the circuit board. After the interrupter is energized, various components in the interrupter are automatically detected. If it is found that the interrupter has come to the end of its life, the reset button will be prevented from resetting, so that neither the load end of the interrupter nor the power output holes on the surface of the interrupter have any power output. This invention has powerful applications, with sound safety precautions, thus effectively ensuring the personal safety of the user as well as the safety of the appliances.
