| 摘要 |
The invention concerns an electrical device (1), consisting of a circuit provided with lighting means (2) and power supply means, at least one rechargeable battery (4), and first (5) and second (6) supplies to an electrical network, said first supply (5) being linked to said battery (4), said circuit further comprising an electromagnetic relay (10), characterised by the fact that said relay (10) comprises a first terminal (11) to which said lighting means (2) are connected; a second terminal (12) to which the second supply (6) is connected; a third terminal (13) to which said battery (4) is connected; said relay (10) comprising an electromagnetic switch (14) linked at a first point (15) to said battery (4) and at a second point (16) to said first supply (5), such that a potential difference between said first (15) and second (16) points results in the actuation of said switch (14). |
