Sold by VLiteMall · Accra New Town

A Card Holder – Energy Saving Switch is a device, commonly used in hotels and student accommodations, that controls power to a room's electrical circuits by requiring a specific key card to be inserted into its slot to activate power. When the guest leaves and removes the card, the switch deactivates the power after a short delay, shutting off lights, air conditioning, and other electronics to prevent energy waste and reduce costs.
