The hotel energy saving switch is specially designed for the hotel business, is one of the optional items of the hotel key card door lock system, and is also suitable for apartments, schools, offices, and other scenes. By reading this article, you will get a complete guide to power switches, to determine if the power switch is necessary for your hotel.

The hotel energy-saving switch is a simple energy-saving solution for hotels. You might think it would be more economical not to buy this, but using energy-saving switches will save more for your hotel. Let’s analyze it together.

Reason 1: Switching benefit.

Due to the integration of the system, hotel power-saving switches and door locks can share a card. When the guest moves the card from the key card power switch, the room power will be automatically cut off.

In this way, all electronic equipment in the room is closed when the guest leaves the room and takes the key card. Effectively avoid the situation of power waste, and achieve the effect of power saving and emission reduction.

Reason 2: Make your guest room safer.

If guests leave their room without turning off the electrical appliances of the room, the waiters do not notice this situation. The electric appliances in the room will continue to operate for a long time, which will cause the heating of the electrical appliances. If the electrical appliances are too hot, they will burn out, and even cause the fire disaster.

Reason 3: Bring economic benefits to the hotel.

Install the electrical essential card switch will bring economic benefits to your hotel, here will show you an example:

Suppose your hotel room has the following electrical appliances:

Left and right bedside lamp: 25~40w*2
Mirror Headlight: 20w
Floor lamp: 25~40w
TV: 120w
Table lamp: 25~40w
Gallery light: 25w
Split air conditioning: 1000w
Total power: 1300w = 1.3kw

If your hotel has 100 rooms, and the electricity unit is USD 0.1 per kWh. With the energy power saving, each room only needs to save 1 hour of electricity per day on average, and the hotel can save electricity cost for: 1.3kw×100 rooms×1 hour/day×365days×USD 0.1/kWh of electricity=USD 4745 per year.

Reason 4: Avoid your room being sold secretly.

We have have a specific energy saving switch, which can help you monitor power consumption of each room. If this room is not sold out, but it did cause a lot of power consumption, you bet the room might be sold out by some staffs. 

Reason 5: help you remind guest to checkout as soon as possible. 

If your hotel always have checkout delay, you could activate the time control function. The switch will turn off the room power supply after checkout time reaches. And if guest keeps staying in the room, they cannot use the electric appliance inside. And you could reconnect the power supply for them remotely if they extend their stay again.

Types of hotel energy saving switches and their development history.

According to the different access card types used by the hotel lock, the power switch can be divided into: mechanical power switch, magnetic card power switch, IC card power switch, low-frequency card power switch, high-frequency card power switch, verify room number power switch, verify check-in time power switch.

Mechanical power switch

The mechanical power switch is an early energy-saving switch, by inserting the key plate, the room power will be connected. In this way, as soon as the guest leaves the room and pulls out the key plate, the power connection will be disconnected and the electricity will be turned off.

Nonetheless, this type of power switch cannot achieve real energy savings and electric device safety. Because hotel guests familiar with this principle can use other items similar to key plates to insert switches to get room power. So the mechanical power switch has been eliminated from the modern market.

The principle of magnetic card power switch is to control the on-off of the infrared rays by inserting the magnetic card. The power switch of this principle is also called general power switch. There still have a few hotels use it.

IC card power switch

IC card power switch gets power mainly by contact IC card. Specifically, mainly by checking the chip pins of the IC card, to judge whether there is a card inserted and whether is an IC card to output the power on and off. The current market share is also relatively small.

Low-frequency card power switch

Low-frequency card power switch is mainly suitable for 125KHz contactless proximity cards, such as EM, TEMIC, IT, and other proximity cards. It mainly checks whether the frequency of the card is in line with 125KHz to control room electricity. It has a large market share.

High-frequency card power switch

It is mainly suitable for 13.56MHz high-frequency identification cards, such as Mifare s70, s50, etc. This type of switch gets power by identifying whether the ID of such cards meets the standard. It is the most used in the current market.
