Device for supplying electric power to a power consumer in dependence of a signal from a movement detector (3) comprising an electrically conducting element (8) which is moved between a first electric terminal and a second electric terminal. Said electrically conducting element (8) connects at an electric connection between either of said terminals (11, 12) to a first signal conductor (9). Said first signal conductor is operatively connected to a trigger input (10) of a triggable circuit (13) included in said movement detector, said circuit having at least one stable condition and at least one metastable condition for driving said triggable circuit (13) from a stable condition to a metastable condition. An output (14) of said triggable circuit (13) is operatively connected to said power consumer (7) for supplying electric power to said power consumer (7) when said triggable circuit (13) is in said metastable condition. |
