The utility model further technical scheme is: described supply socket circuit is positioned at the lower left of plastic casing, described self locked energy-saving circuit is positioned at the left side of supply socket circuit, the top of supply socket circuit connects with the left end of I electric capacity, the right-hand member of I electric capacity connects with the left end of I crystal diode, and the right-hand member of other I electric capacity also connects with the upper end of II crystal diode.

The utility model further technical scheme is: the anti-interference discharge circuit of described time delay is positioned at the right of plastic casing, the right-hand member of II crystal diode connects with the upper end of II electric capacity, the lower end of the second electric capacity connects with the lower end of I I crystal diode, the right-hand member of II crystal diode also connects with the left end of carbon film resistor, the right-hand member of carbon film resistor connects with the below of bidirectional thyristor, the below of bidirectional thyristor also connects with the lower end of II electric capacity, the top of bidirectional thyristor connects with the upper end of self-lock switch, the lower end of self-lock switch connects with the below of bidirectional thyristor, the upper end of bidirectional thyristor and the upper termination 220V AC power of supply socket circuit.

The utility model compared with prior art has following features:

1, the one power failure energy-saving switch that provides of the utility model, its structure is simple, and have memory function, it can cut off the current supply circuit of electrical equipment automatically, avoids the power wastage that causes because owner forgets to close mains switch and electrical fire;

2, this circuit production is easy, installs reliable, and low price, widely applicable.

Be further described below in conjunction with the detailed construction of the drawings and specific embodiments to utility model.

Accompanying drawing explanation
