How long has the room card been unplugged?

The power will be cut off within about 15 seconds after the hotel room card is pulled out.

When staying in a hotel, the key card is always inserted, which has two advantages. First, it can be electrified by plugging in the power supply, so as to prevent the waste caused by keeping the electric appliance on when no one is around. The second is to put it at the door to prevent you from losing your key card when you check in and unable to check out. Now the design of the hotel is to plug in the key card before it can be officially powered on. This is an advanced design concept, so it must be inserted all the time.

The room card is also called the power switch.

Power switch is an energy-saving product specially designed for hotel rooms. Hotel guests can use the lighting, TV, air conditioning and other equipment in the room by inserting the door card into the power switch of the special card when entering the room, and take out the door card when leaving the room (guests must pull out the door card when going out, because they need the door card to open the door when returning to the room).

The main power supply of the room can be automatically cut off within 15 seconds, which saves electricity and makes the room safer. Generally, the power take-off switch is powered by high voltage 220V, equipped with high power 30A relay, and the load is 6600W, which can meet the power load of hotel rooms. There is a luminous LED blue light indicator on the power switch, which conforms to the trend of modern hotels and is convenient for guests to operate at night.

In order to make the hotel room achieve better power-saving effect, more special cards are used to get electricity from the power switch. Only by inserting a special card that matches the door opening card of the hotel doorbell can you get electricity, and the same card can open the door to get electricity.
