One-key control single-phase mains supply output device

The utility model discloses a one-key control single-phase commercial power output device. An MCU (Microprogrammed Control Unit) singlechip is taken as a center, and the MCU is connected with a key switch circuit, a single-phase mains supply output circuit and an overcurrent detection circuit. And the key switch circuit is formed by connecting a key switch with a pull-up resistor in series. When the key is pressed, the MCU controls the output of the single-phase mains supply and determines the delay duration of the output of the mains supply; and in case of overcurrent, the MCU sends out a mains supply output closing signal to close the mains supply output. Single-phase mains supply can be output only by pressing a key, the use is simple, and the problems that individual old people who cannot use smart phones cannot use a code scanning electric motorcycle shared charging pile conveniently, and the shared charging pile is inconvenient to install in places without mobile phone network signals can be solved; and
