Embodiment 1
[0021] refer to figure 1 , this embodiment takes three live wire output terminals as an example. The light touch electronic power switch circuit in this embodiment includes a power live wire input terminal LIN and three power supply live wire output terminals (LOUT1, LOUT2, LOUT3). Each power output terminal passes through An electromagnetic switch is connected to the input terminal of the power supply. The electromagnetic switch is controlled by the trigger storage circuit. The input terminal of the trigger storage circuit is connected with light touch buttons (K1, K2, K3). The solenoid switch state changes once. The light touch electronic power switch circuit also includes a voltage stabilized power supply circuit that provides DC regulated power for each trigger storage circuit. Theoretically, the number of live wire output terminals of the light touch electronic power switch circuit of the present invention can be expanded arbitrarily according to needs.
