Can the hotel use other cards instead of plug-in cards to get electricity?
When you plug in the power switch with something other than your room card, and you can't get electricity, you can go to the front desk of the hotel to apply for a room card or a power card, so that people can go out temporarily and the appliances in the room can still work normally.
When the power switch identification card is successful, how to proceed to the next step?
Inside the power switch, there is an integrated circuit board with a key component-micro relay, which controls the power supply. When the switch successfully identifies the card, it will automatically send a signal to the microswitch. After the microswitch is turned on, the relay coil is energized, and the relay is attracted to start power supply. After the card is pulled out, the microswitch is turned off, the contactor coil is powered off and the room is powered off.
