Let’s try to learn More About the Hotel key card power switch!

Here is a complete guide article to help you know the key card hotel energy-saving switch clearly. By the end of this guide, you will understand how to choose the right hotel energy-saving switch to save more power.

What is a hotel energy-saving switch?

The smart key card hotel energy-saving switch adopts a high-frequency card (13.56Mkz, Mifare card) or low-frequency card (Temin card–E5557, E5567, EM card, etc.) to take power.

Only when the hotel guests insert the corresponding hotel key card into the key card energy-saving switch will the hotel room be powered, effectively achieving hotel energy saving?

What is Key Card Hotel Energy Saving Switch? And how does it save power for hotels? 2

The key card hotel energy-saving switch is installed on the doorway’s sidewall in the guest room.

When the guest checks in, the guest inserts the room card (door opening card) into the hotel card switch, and the total power in the room is turned on. Remove the room card; the power will be powered off after 8-15 seconds.

More dedicated RFID cards are used to get electricity from the hotel energy-saving switch to achieve energy efficiency in hotels.

Only by inserting the dedicated card that matches the hotel room door to get electricity can the same card be realized to open the door and get electricity.

Card key hotel energy-saving switches are increasingly being used in hotel lock systems, and they are now an essential part of all-in-one card hotel lock systems.

Why do you need hotel energy-saving switches?

The power hotel energy-saving switch is a product specially designed for various hotels, motels, apartments, and office buildings.

It is mainly used to solve the problem of cutting off the power supply when no one is in the hotel room to achieve electrical safety and energy saving.

When a hotel guest enters the room, insert the hotel room card into the key card hotel energy-saving switch to use the room’s lighting, TV, air-conditioning, and other equipment.

When the guest leaves the room, take out the hotel room card (the guest must pull out of the room when going out because the guest room needs a door card to open when returning to the guest room).

The room’s total power supply will automatically be turned off within 15 seconds, saving electricity and making the guest room safer. If you want to re-power on, insert the room card again.

More energy saving for hotels

If the hotel uses key card power switches, How about energy efficiency in hotels?

According to the electrical configuration of the available standard guest room, the power of each electrical appliance in the room is about:

  • Left and right bedside lamp: 25~40W*2
  • Mirror front light: 20W
  • Floor lamp: 25~40W
  • TV: 120W
  • Table lamp: 25~40W
  • Gallery light: 25W
  • Split air conditioner: 1000W
  • The total power is about 1300W=1.3KW.

According to this power calculation, if the hotel has 100 rooms, each electricity unit is 0.1 US dollars, and each room only needs to save 1 hour of electricity per day.

After adopting the select key card light switch, the hotel will annually save electricity costs: 1.3 kilowatts × 100 rooms × 1 hour/day × 365 days × 0.1 US dollars / per kilowatt-hour = 4745 US dollars.

ShineACS Mifare Key Card Hotel Energy Saving Switch

So, if your hotel doesn’t use a key card power switch for your hotel, please consider upgrading your hotel lock system and adding a power switch that works with it to save more electricity.

The hotel’s energy-saving switch can bring electricity safety to the hotel.

If guests go out without turning off the hotel’s electrical appliances, and the hotel staff has not noticed this, it will cause their electrical devices to work for a long time.

Long-term operation of electrical appliances can generate heat within the telephone itself, leading to burnout and even fire.

The hotel energy-saving solutions can not only bring direct economic benefits to the hotel (saving significant amounts of electricity bills), extend the life of the room electrical appliances, improve the safety factor of the room electricity,

but also achieve the hotel’s significant energy savings with the least investment cost and complete the “energy saving” effect of reducing emissions.

What are the types of hotel energy-saving switches?

According to the different card types used in hotel door locks, the power key card switch is divided into the mechanical hotel energy-saving switch, 13.56Mhz Mifare energy-saving switch, hotel magnetic card switch, and 125Khz hotel key card switch.

1) Mechanical hotel energy-saving switch:

What is Key Card Hotel Energy Saving Switch? And how does it save power for hotels? 3

The early power energy-saving light switch was a mechanical rocker switch. The two contacts of the power supply were turned on by inserting the key plate. Therefore, the connection is disconnected when the guest leaves the room, and the power supply is cut off when the key plate is taken out.

Hotel guests familiar with this principle sometimes use combs and other complex pieces like keyplates to insert switches, which can also generate electricity. Therefore, electricity safety and energy saving cannot be fundamentally solved. It has almost been eliminated.

2) 13.56Mhz Mifare energy-saving switch:

Mifare energy saver key card switches are mainly suitable for 13.56MHz high-frequency RFID cards, such as MIFARE S70, S50, domestic Fudan cards, etc.,

Identify whether the ID of this type of card meets the standard to output power on and off. Currently, Mifare hotel energy-saving switches are mainly used in the market.

3) 125Khz hotel key card switch:

It is suitable for 125KHz non-contact proximity cards, such as EM TEMIC 5557. 5567, TI, and other proximity cards. It mainly detects the card’s frequency and whether it conforms to 125KHz to output the power on and off. The current market share is relatively large.

The above three types are the more common key card power switches. Also, there are identifying room numbers and identifying time types. 

4) Recognizing room number type hotel energy saving switch: It is one of the unique controls for outstanding cards. It reads the room address data in the door-free card and compares whether the room’s card outputs the power on and off.

But just a tiny number of hotels use it. 

5) Recognizing the time type power switch: it is also one of the unique key card switches for the hotel. It outputs the power on and off by reading the room address and time data in the door opening card to compare whether it is a card within the room’s correct time. A few hotels use it. 

How to install a hotel key card switch?

ShineACS locks provide detailed installation instructions and wiring guidelines to help you install the hotel key card switches correctly and safely; please refer to the following video:

Please note:

1. Please be careful not to let the wire squeeze into the relay at the back of the switch during installation. Otherwise, the hotel room key card switch will not be powered down.

2. Please be sure to install the key card switch for the hotel in the case of power failure

3. If the hotel key card switch is not working or no card can be powered, please re-install the wiring once.

4. The first power-up of the hotel room key card power switch will have a standard Initialization action(with electrical output). After installation, open the card out of the strip to prevent dust from falling into the card socket caused by the power.

5, Hotel total power In a single room that exceeds 6000W, purchasing an AC contactor separately is recommended to avoid causing the energy-saving hotel card key switch to burn out.

How to hack a hotel key card power switch?

Depending on the hotel key card power switch you use for your hotel room, it’s easy to hack the power switch and replace the restrictions on hotel room cards.

For example, if your hotel room uses optocoupled hotel key card switches, plug in any suitable card that can power the room.

If you use a Mifare hotel key card switch, inserting the corresponding Mifare card can also supply power to the room. For example, some countries’ ID cards and bank cards are also Mifare cards.

Therefore, if you want to avoid hacking the key card power switch and wasting electricity as much as possible, it is recommended to use a one-to-one power switch that identifies the room number; the room door can only use the power switch of this room.

Hotel card key switch price 

The price of a hotel key card power switch is the following:

  • A 13.56 Mhz Mifare RFID key card power switch costs $15-$35 per unit.
  • A 125Khz ID RFID key card power switch costs $10-$25 per unit.
  • A standard optocoupler hotel key card switch price is generally $5-$15 per unit.
  • A one-to-one hotel key power switch that identifies the room number is generally about $25-$40 per unit.

The composition of the Hotel energy-saving switch:

Generally, the hotel energy-saving key card system comprises three parts: high and low-voltage power conversion, identification card, and output.

There are many power conversion ways, such as switching power supply, resistance-capacitance step-down, transformer, etc.

composition of the Hotel energy-saving switch

The high and low voltage conversion part converts the AC power to DC transient voltage power supply through rectification and stepping down.

The identification and output parts identify the card part by detecting whether the inserted card meets the preset standard. The output part gets the standard signal of the identification card part. The AC power is turned on (FireWire).

Supplement: The hotel room power switch can be 30A, 40A, etc. According to the different load requirements of the hotel room.

What’s the difference between the hotel energy-saving switch and the ordinary panel switch:

According to the principle and structure of the hotel energy-saving switch, the hotel key switch is compared with the ordinary panel switch:


  • All rely on the on-off circuit to achieve the purpose of control, and the power is all firewire.
  • The wiring method is the same; the switch controls the fire but not the zero.
  • Note: Ordinary panel switches generally have only two wires: live wire in and live wire out, while card energy-saving power switches typically have three wires: live wire in, live wire off, and zero wire.


  • The structure is different: Ordinary switches are mechanically pressed to open and close. The automatic identification card system controls the hotel power card switch. The focus is on control, and it has relays, rectifier modules, and small transformers.
  • Different applications: General lighting panel switches generally exist alone in the branch control of household electricity, for example, control a single light. The hotel’s critical card switch is usually installed in the hotel room’s central road control. It manages all electrical appliances in the hotel, similar to an air switch.
  • The function is different: Ordinary power panel switches only have the switch function. The electrical card switch weakens current information identification, power-off delay, and control function.
