Apparatus for controlling electrical receivers occupying at least two states

Apparatus for controlling a plurality of electrical devices each able to occupy at least two states, comprising individual control means connected to a power supply associated respectively with said devices, each individual control means comprising switching means for positioning the corresponding electrical device in any one of its states, and general control means connected to the power supply, comprising switching means for positioning all the electrical devices in any one of their states,

• characterised in that each individual control means comprises a logic processing unit permanently connected to the power supply and comprising first and second groups of input terminals, the first group of input terminals including at least one input terminal to which is connected the switching means of said individual control means, said logic processing unit also comprising output terminals connected to the corresponding electrical device, the switching means of the general control device being connected to said second group of input terminals provided on each logic processing unit each logic processing unit accepting commands given non-simultaneously by the corresponding individual control means or by the general control means and accepting only the command given by the general control means when such command is given simultaneously with a command from the corresponding individual control means.
