Abstract
The device for controlling electrical loads, in timed mode or in another mode, for example for illuminating stairs inside a building, electrically operated locks, etc. The device comprises a unit A which supplies, following the pressing of at least one push button P1-Pn, a unit X which can send, independently of the time for which the aforesaid push button is kept pressed, a pulse of predetermined duration for the control, through further units B and C connected in cascade to the unit X and operated by it, of a corresponding load D. The unit X is activated only in the presence of a predetermined active front of a signal VA originated by the push button P1-Pn. In a second embodiment, the device comprises a unit X' provided as an alternative to the aforesaid unit X described with respect to the first embodiment, associated with a unit Y capable of keeping the load D constantly activated when predetermined first and second operating conditions are present. <IMAGE>
