Field of the invention

The present invention relates to the field of electronic electrical control devices, for example with the function of switch or diverter.

More specifically, the invention relates to the sector of smart electronic electrical devices, i.e., operated by means of digital electronic means adapted to communicate with a remote electronic control system.

Prior art

The control switches currently on the market may be classified into three distinct families:

- conventional type, only manual switches with a mechanical element that acts on the electrical contact for exclusive use in conventional systems with direct control on the power circuit;

- electromechanical type only, operated by means of an auxiliary control circuit by means of a magnetic coil for use in control systems with electromechanical relays/contactors;

- digital electronic type, operated by means of a digital communication system, in particular adapted to communicate with a remote electronic control system.

If a switch of the digital electronic type is adopted, the issue of the reliability of the electronic part and the communication part arises. Furthermore, there is a second issue of impossibility of acting on the control itself in a mechanical manner, except by means of control systems that block the possibility of subsequently sending the command back by means of the electronics. Such issue occurs, in particular, when upgrading existing systems with the adoption of digital electronic solutions.

The prior art does not include the possibility of mechanically acting on the device without forcing the electronic part. There are no devices that combine the two modes (mechanical and electronic) in an undifferentiated manner. Currently known devices provided with a manual control act as a forcing with respect to the digital electronic control, or smart control. Known smart controls, in the event of a failure or lack of connectivity, are inhibited and therefore the user has difficulty or is unable to control the electrical load. Therefore, the need is felt to overcome the limits of the prior art.

In particular, the need is felt for a device offering a greater versatility of use. Summary of the invention

It is an object of the present invention to produce an electronic electrical control device that is more versatile with respect to the prior art.

In particular, it is an object of the present invention to provide an electronic electrical control device that may be operated even when the electronic part may not be controlled.

The present invention achieves at least one of such objects and other objects that will become apparent in light of the present description, by means of an electronic electrical device comprising

- a first electrical conductor for the input of electric current;

- a second electrical conductor for the output of electric current;

- a first electrical control device adapted to have two positions to electrically connect and disconnect the first electrical conductor and the second electrical conductor to/from each other;

- a second electrical control device adapted to have two positions to electrically connect and disconnect the first electrical conductor and the second electrical conductor to/from each other;

- first actuation means comprising a digital electronic controller;

- second actuation means comprising only mechanical and/or electromechanical components; wherein the first actuation means are adapted to vary the position of said first electrical control device independently of said second actuation means; and wherein the second actuation means are adapted to vary the position of said second electrical control device independently of said first actuation means. The invention also relates to an electrical socket, in particular a controlled electrical socket, according to claim 14.

Advantageously, the electronic electrical device may be controlled, or operated, both by means of the first actuation means and by means of the second actuation means.

Advantageously, therefore, in the event of failure of the first actuation means, for 3 example, in the event of failure of the digital electronic controller, or in case of lack of connection with the communication network, or in the absence of the communication system, the electronic electrical device may be controlled by means of the second actuation means.

In fact, advantageously, the second actuation means comprise only mechanical and/or electromechanical components, and in particular they are not controlled by any electronic component.

Advantageously, the first actuation means and the second actuation means may be operated indifferently, without one excluding the other.

Furthermore, the electronic electrical device offers the possibility of being controlled exclusively by means of the first actuation means or exclusively by means of the second actuation means.

Advantageously, the second actuation means are redundant with respect to the first actuation means.

The electronic electrical device may be of the unipolar type or of the multipolar type. By way of example and not by way of limitation, the electronic electrical device may function as: a compact cable control switch (for example, as a switch for a table lamp); a socket control switch to be placed in conventional and standardized sockets; a DIN rail control switch, to be placed on electrical switchboards; a control switch integrated into a smart socket which may be controlled with a manual control switch.

Exclusively by way of example, the electronic part of the electronic electrical device may be electrically powered by: 230 V mains voltage, in particular in the case where a phase-neutral bipolar connection is provided; or the voltage of a control BUS, in particular when a connection to a wired BUS system is provided; or by means of an internal battery.

The electronic electrical device is particularly suitable both for applications in the home automation sector as well as in the industrial sector.

The electronic electrical device may be used both in a newly built system as well as in the upgrading of systems, while maintaining the existing wiring so as to digitize the controls while maintaining the existing control points.

Further features and advantages of the invention will become more apparent in the 4 light of the detailed description of exemplary but not exclusive embodiments. The dependent claims describe particular embodiments of the invention.

In another example (Figure 5-8), said second electrical control device 2’ is an electric inverter; and the electronic electrical device 100’ is configured to function as an electric diverter.

In particular, the electronic electrical device 100’ comprises a further electrical conductor 39 for the output of electric current; and the electronic electrical device 100’ is configured so that, depending on the position taken by the first electrical control device 1 and by the second electrical control device 2’ (i.e., by the electric inverter), the first electrical conductor 31 is electrically connected to the second electrical conductor 32 and electrically disconnected from said further electrical conductor 39 (Figure 5 and Figure 7), or the first electrical conductor 31 is electrically connected to said further electrical 6 conductor 39 and electrically disconnected from said second electrical conductor 32 (Figure 6 and Figure 8).

In particular, advantageously, the electronic electrical device 100’, depending on the position of the first electrical control device 1 and of the second electrical control device 2’, may have two distinct configurations in which the first electrical conductor 31 is electrically connected to the second electrical conductor 32 and electrically disconnected from said further electrical conductor 39, and two distinct configurations in which the first electrical conductor 31 is electrically connected to said further electrical conductor 39 and electrically disconnected from said second electrical conductor 32.

When the first electrical control device 1 is in the second position and the second electrical control device 2 is in the first position, the first electrical conductor 31 and the second electrical conductor 32 are electrically disconnected from each other (Figure 2).

Advantageously, the fifth electrical conductor 35 may be moved by the first actuation means 10 to be alternatively connected to the electrical conductor 33 or to the electrical conductor 34, independently of the second actuation means 20. Advantageously, furthermore, the sixth electrical conductor 36 may be moved by the second actuation means 20 to be alternatively connected to the electrical conductor 33 or to the electrical conductor 34, independently of the first actuation means 10.
