Abstract
A socket includes: an input terminal configured to be electrically connected to an AC power source; an output terminal configured to output an AC signal of the AC power supply; a switch circuit electrically connected between the input terminal and the output terminal; a step-down circuit electrically connected to the input terminal and configured to reduce the amplitude of the AC signal; a shaping circuit electrically connected to the step-down circuit and configured to convert the AC signal with reduced amplitude into a shaped signal; and a control circuit electrically connected to the shaping circuit and the switch circuit and configured to control the switch circuit based on the shaping signal to enable the switch circuit performs switching operation only when the AC signal is at zero potential. A door includes the socket.
