Hotel Key Card Energy Saving Switch 125KHz/13.56MHz 110V/220V
Hotel Key Card Energy Saving Switch 125KHz/13.56MHz 110V/220V
Hotel Key Card Energy Saving Switch — Dual Frequency, Wide Voltage
Upgrade your hotel, motel, or accommodation property with this intelligent Hotel Key Card Energy Saving Switch by Asia-Teco (Model ES3). Supporting both low-frequency (125KHz) and high-frequency (13.56MHz) RFID cards, this smart wall switch automatically controls room power based on card presence — cutting electricity waste and reducing operating costs effortlessly.
Made in Mainland China.
How It Works
- Card-In = Power ON: When a guest inserts their room key card into the card slot, the switch detects the card and activates the room's full power supply — lights, air conditioning, TV, and more.
- Card-Out = Power OFF: When the guest removes the card upon leaving, the switch automatically cuts all room power after a brief delay, preventing unnecessary energy consumption.
- Dual Frequency Support: Works with 125KHz low-frequency cards (EM4100, EM4305, T5557/T5577, TEMIC, TI, ID cards) and 13.56MHz high-frequency cards (M1/Mifare and compatible).

Frequently Asked Questions
Q: What types of key cards are compatible with this hotel energy saving switch?
A: This switch supports both low-frequency (125KHz) and high-frequency (13.56MHz) RFID key cards. Compatible low-frequency cards include EM4100, EM4305, T5557, T5577, TEMIC, and standard ID cards. High-frequency compatible cards include M1 (Mifare) and other 13.56MHz induction cards.
Q: Can this switch be used with both 110V and 220V electrical systems?
A: Yes. This is a wide-voltage switch designed to work with AC 110V and AC 220V systems, making it suitable for hotels and properties in virtually any country. DC 5V and 12V configurations are also available, and custom voltages can be arranged.
Q: How is this hotel key card switch installed?
A: The switch uses standard 86mm × 86mm wall box mounting with left/right installation — the same as most standard wall switches. The ultra-slim 29mm bottom box height makes it easy to fit into existing wall boxes without modification in most cases.
Q: What happens when a guest removes their key card from the slot?
A: When the key card is removed from the card slot, the switch initiates an automatic power-off sequence after a brief 10–15 second delay. This cuts power to all connected room devices, including lights, air conditioning, and the TV, ensuring no energy is wasted after the guest leaves.
Q: Is this switch available in different load capacities and colors?
A: Yes. The ES3 is available in three load capacities: 40A (8,800W), 60A (13,200W), and 90A (18,000W). Standard colors include white, black, gray, and rose gold, with custom color options available upon request.
