POWER SAVING CIRCUIT FOR LIGHTING FIXTURES LOCATED IN COMMON AREAS IN DWELLINGS

摘要

The invention comprises the incorporation of a circuit associated with the parallel connection nodes of the lighting circuits of each floor, which nodes are connected to the automatic stairwell circuit. The above-mentioned circuit includes a pair of relays (9-10) of the type that comprise a pair of contacts (91- 92, 101, 102) for powering a coil with a magnetisable core, which coil is used to control the electric communication between pairs of connectors associated with each relay, such that the aforementioned circuit is placed in the circuit for powering the lighting circuit for each floor. As a result, electrical continuity can only be obtained by pressing the corresponding push button (51, 52, 53, etc.) associated with each floor, which push button is associated with the input (91) of the coil of the first relay (9), thereby closing the corresponding electrical contacts associated with the circuit of said floor, the rest of the floors remaining unlit until the corresponding push button thereof (51, 52, 53, etc.) is pressed.
