How does a Key Card Switch Work?



Key Card Switches are generally used in hotels and high end condominiums.  After check-in verification in hotels, the front desk personnel will give the guest a key card to his/her assigned room. Upon getting into the assigned room and inserting the key card in a key card slot by the main door of the room, all the lights and other controlled circuits will automatically turn on. Upon leaving the room, guests remove the key card and the lights and other controlled circuits will turn off after a standby delay of a few seconds. This is to ensure that the guest/s have safely exited the room before the power turns off. Aside from the aesthetically appealing design, hospitality establishments install key card switches to help reduce energy costs. This is because all lighting, heating and power (aside from the refrigerator) circuits only become operational once the card is inserted in the key card slot.





A little known fact for hotel guests is that in order for a key card switch to effectively operate, it needs a control panel. The Meiji Home Panel with Key Card Control has circuit breakers, timer/s and magnetic contactor/s to effectively operate Key Card Switches commonly installed in hospitality establishments. A magnetic contactor is a switchgear device that is like a relay but has a higher current capacity. It is mechanically and electrically durable to withstand frequent switching on and off operations with high power. The housing of the Meiji Home Panel with Key Card Control is a modular powder coated metal distribution box applicable for electric circuit terminals rated at 220/400V, 60Hz. The cover is made of special fire retardant, impact resistant ABS PC alloy material with slot/s for timer/s and magnetic contactor/s.  Various hotels in the Philippines have already installed this in their individual rooms so you are sure of its safety and durability.

    Hi I have a 1 unit in my city which i am building . I was looking for electrical switch key circuit that can automatically open the 6 light 4 outlet 1 water heater, 1 refrigerator and 1 aircon. Does this electrical switch key circuit support or have terminals that has at least 2 circuit for minimal load and 3 circuits for high loads.

    so i can save electricity when my guests are out of the unit. Please send me a quotation about the maximum ampere and how many outgoing terminal it has and if it can support high load and for the price. Thank you
