Abstract: The invention concerns a controlling device (10) having terminals for connection to an electrical circuit (11) comprising: a first user device (12) energized by a first voltage power supply and configured to switch between at least an on-state and an off-state, a second user device (13) configured to be connected in series with the first device (12) and energized by a second voltage or current power supply, the controlling device (10) being configured to be connected in parallel of the first user device (12) and to: absorb a leakage current flowing through the electrical circuit (11) below a first predetermined threshold, and control the voltage or current between the terminals of the controlling device (10), so as to ensure that the second user device (13) is supplied with the second voltage or current.
