However, it does not support the network boot function without power, but supports the shutdown function.

The main controller 4 is further provided with a second timer, which starts timing when the power input end is disconnected from the power output end, and if it detects that the power is detected before the second preset timeout ends In operation, the first timer is reset to zero; otherwise, when the timing of the second preset value ends, the backup power source 5 is turned off.

It should be noted that the first preset timing period of the first timer and the pre-design time period of the second timer may be set or modified by an input device (for example, a remote control device).

It should be noted that the backup power source 5 can be configured as an in-machine backup power source and an off-board backup power source. The in-machine backup power source is a large-capacity capacitor, and the off-board backup power source is a chargeable and dischargeable energy block. It contains a charge and discharge management circuit. The principle of the embodiment in which the magnetic holding relay in the power switching device is a two-coil magnetic holding relay is the same as the embodiment in which the magnetic holding relay is a two-coil magnetic holding relay, and details are not described herein again.

It can be understood that the above-mentioned main controller 4, backup power supply 5 and network switch control circuit 60 or remote control receiving switch control circuit 61 or remote switch control circuit 62, backup power supply 5, and first timer and second timer can be used. It is applied to the various embodiments of Figures 1 to 3.

The above scheme is adopted, and the electrical switch machine where the power switch device of the present invention is located is ensured to work normally. When the backup power source 5 is valid, manual on/off, timed on/off, and automatic on/off can be easily realized. Remote on/off, network on/off, inductive on/off, and their on/off command levels are the same, on a first-come, first-served basis, and standby power consumption is zero after shutdown.

The power switch device according to claim 9, wherein the backup power source is configured as an in-machine backup power source and an off-board backup power source, wherein the in-machine backup power source is a large-capacity capacitor, and the off-board backup power source is A charge and discharge energy block, wherein the energy block includes a charge and discharge management circuit.

The power switch device according to claim 3, wherein the manual switch comprises a manual push rod, first and second gears that are engaged with each other, a first push rod and a second push rod, and a third push a rod; the first gear and the second gear are each provided with a rotating shaft, the one-way gear is at a lower portion of the first gear and rotatable about a rotating shaft of the first gear; the first push rod and the first gear a spring is disposed between the second push rod and the second gear; the manual push rod is engaged with the first gear through a one-way gear; when the manual push rod is pressed, Driving the one-way gear and rotating the first gear, the first gear drives the second gear to rotate, the direction of rotation is the opposite direction, the first push rod rotates with the first gear, and the second The push rod rotates with the second gear, the spring force of the spring is much smaller than the switching resistance of the coil magnetic holding relay contact switch, and the third push rod is horizontally moved when the thrust exceeds the switching resistance, thereby The coil magnetic holding relay The point switch is closed or opened; when the manual push rod is released, it is reset by a return spring, and the first gear or the second gear is abutted by a limiting device; when the return spring is reset The first push rod and the second push rod are outside the sliding range of the third push rod.

The power switch device according to any one of claims 2 to 4, wherein the power switch device is disposed in a power adapter, and the power adapter receives the control signal through a physical connection. The control signal is a positive/negative pulse signal, or a high/low level signal.

The power switch device according to claim 12, wherein when the power adapter is disconnected from the connected appliance, a high/low level control signal is generated to cause the second coil driving circuit to generate the first pulse Driving the coil in the coil magnetic holding relay to disconnect the contact switch, disconnecting the power input from the power output.
