By placing a magnetic keyring in the socket, power is supplied to the hotel room and the power is disconnected after a few seconds. The economizer consists of a magnetic socket, a magnetic key chain, a high power relay circuit with time delay for lighting control and air conditioning
The key ring is made of ‘solid’ European bronze, on which the logo of the hotel is engraved and can be nickel-plated or gold-plated. The magnetic socket is installed near the entrance of the room and has a light to illuminate.
The economiser is easily installed in existing electrical installations, without any special temperament, and its operation is now safe (12V D.C.) and completely silent.
