Abstract: An alternating current/direct current input device includes an appliance input socket and an information and communications technology (ICT) device. The ICT device is powered by the appliance input socket. The appliance input socket includes a ground contact, a positive electrode contact, a negative electrode contact, and a signal switch. A contact depth of the signal switch in the appliance input socket is less than a contact depth of the positive electrode contact or the negative electrode contact in the appliance input socket. The signal switch is configured to generate a control signal when a direct current connector is separated from the appliance input socket. The control signal can be used to enable the ICT device to disconnect the appliance input socket from a conductive electrode of the direct current connector after the ICT device enters a no load state.
