In figures 1 and 2, 1 indicates the relay adapter system 5 electromechanical, with 10 the adapter module and with 30 the system power supply according to the present invention. The power supply system 30 comprises a plurality of relays 100 of the type electromechanical stepper type, one power line A, implicitly including a phase line L and a related phase line 10 neutral N of the electric current, a plurality of control devices P each configured to operate a related relay 100 connected to a respective electrical load Z and to the adapter system 1, as will be described in more detail below. In preferred embodiments, the adapter module 10 comprises a 15 plurality of connection terminals 21, 22, 23, 24, 25 configured for connect the same adapter module 10 to an electrical circuit 200 comprising a respective electrical load Z, a respective switching device command P and a reset device R. Preferably the module adapter 10 includes second connection terminals 31, 32, 33 20 configured to connect the same adapter module 10 to the corresponding relay electromechanical 100. As illustrated in Figure 1, in some embodiments, the adapter module 10 comprises a control circuit 12 comprising a monostable relay 11 and a plurality of passive electronic devices D1, 25 D2, D3. Each adapter module 10 is interconnected between the relevant relay 100 and the respective P control devices in such a way as to integrate their traditional operation with different control logics for the versatile power supply of the relevant electrical loads Z. 5 Note that each control device P includes a respective control button 104 to operate the relevant electromechanical relay 100 in such a way as to power or disconnect the respective electrical load Z. Electrical loads Z can be identified, for example, as appliances lighting in both residential and industrial settings, while being 10 it is evident that the same concepts can also be applied in the case of other loads, such as the drive system of a roller shutter motorized. Each electrical load Z is respectively connected to the line of power supply A via the respective relay 100, which alternatively 15 powers it and turns it off according to the control logic that will be described in detail below. Each electromechanical relay 100 advantageously comprises a control device T2 and a respective switch I2 operated by it and therefore subservient to it. As will be illustrated in greater detail in 20 Following, the present invention may utilize additional devices control and related switches and, consequently, the control device T2 and the respective switch I2 of the electromechanical relay 100 will be referred to as secondary control device T2 and switch secondary I2. 25 In preferred embodiments, the second control device T2 is an electromagnet which, when powered by the passage of electric current alternately activates the closing or opening of a contact of the second switch I2. As illustrated in figure 1, the line of phase L is connected to each electromechanical relay 100 between the second 5 switch I2 and the second control device T2. Furthermore, each related electrical load Z is connected in series to the related secondary switch I2 of the respective electromechanical relay 100 and also interconnected to the neutral line N. Advantageously, the adapter system 1 of the present invention can 10 comprising one or more reset devices R each operatively interconnected to each electromechanical relay 100 via respective modules adapters 10. In preferred embodiments, the reset device R comprises also a reset button 101 interconnected overall in 15 parallel to the series connection of a signaling device 102, if present, and a respective diode D4. Preferably, each adapter module 10 is configured alternatively to allow or prevent the circulation of current in the second control device T2. Each monostable relay 11 20 comprises a first control device T1 and a first switch I1 operated by the first control device T1 and therefore to it slaved. The monostable relay 11 is, for example, made by means of a opto-triac. The operation of the monostable relay 11 involves a configuration of 25 rest and an operational configuration. Advantageously, according to the idle configuration, the first control device T1 is not powered and the first switch I1 is open. While, according to the operational configuration, the T1 control device is powered and activates the first switch I1 which is closed. 5 The first control device T1 is preferably connected in parallel to the relevant electrical load Z so that it is always powered if the relevant electrical load Z is powered, i.e. if switch I2 is closed. In preferred embodiments, the control circuit 12 comprises a 10 third diode D3 interconnected in series with the related first device T1 command so as to allow one-way passage of current. In some embodiments the control circuit 12 comprises a first diode D1 interconnected in series between the reset device R and the first 15 switch I1. The first diode D1 is advantageously biased so such as to allow only the passage of current in the direction from reset device R to the first switch I1, i.e. in such a way as to allow current to pass from the reset device R to the second T2 control device. Also each adapter module 10 20 includes a second diode D2 connected in parallel to the first switch I1 is polarized so as to allow the passage of current from the second control device T2 to the corresponding control device P. In In some embodiments, the second diode D2 is counter-biased with respect to the first diode D1 and interconnects the second device of 25 command T2 to the relevant control device P even when the relay monostable 11 assumes the rest configuration, that is when the first switch I1 is open. Advantageously each control device P comprises a signaling device 103 and a fifth diode D5 arranged 5 mutually in series and overall in parallel with respect to the relative command button 104. In some embodiments, as illustrated in Figure 1, the first switch I1, the second diode D2, the first diode D1 and the push button command P share a common node C so as to allow, 10 thanks to the mutual counter-polarization between the first diode D1 and the second diode D2 and the alternation between the rest position and the position monostable relay operation, the alternating flow of current in the first diode D1 or in the second diode D2 depending on the configuration assumed from the monostable relay 11 and also depending on the button being pressed 15 reset 101 or pressing the relevant control button 104. According to the described configuration of the circuit diagram of the module adapter 1, adapter system 1 and power system 30, pressing the first button 101 can allow the passage of current to power the second control device T2 only 20 if the monostable relay 11 assumes the operational configuration, i.e. if switch I1 is closed, i.e. only when switch I2 is closed and allows the power supply of the relevant load Z. In fact, the related second control device T2 of the related relay electromechanical 100 must be powered by the drive of the 25 reset button 101 only when the relevant electrical load Z is actually powered by the electrical power source A. If, however, the reset button 101 is operated by a monostable relay 11 assuming the rest configuration, i.e. when the relative load electric Z is not powered, then the second control device T2 5 cannot be powered because the first switch I1 is open. Power supply adapter 1 operation 30 seconds The present invention is described below. As an example, an initial condition is considered in which the second switch I2, the control buttons 104 of the related control devices 10 command P and reset button 101 are all open. By pressing a control button 104 there is electric current from the line flow L which feeds the second control device T2, flowing in the second diode D2 and crossing the same control button 104 closing in a knot on the return line N. 15 The extemporaneous power supply of the second control device T2 causes the second switch I2 to close. The closing of the second switch I2 allows the L delivery line to power at the same time the relative load Z and consequently the first T1 control device interconnected in parallel. The power supply of the 20 first control device T1 causes the monostable relay 11 to assume the operating configuration, i.e. where the first switch I1 is closed, thus providing an additional path, compared to that provided by the second diode D2, for the passage of current. By pressing the control button 104 of a relay again 25 electromechanical powering a relative electrical load Z the second power supply device T2 is powered and therefore the second switch I2 is opened bringing the monostable relay 11 into the rest configuration, i.e. in which switch I1 is open. The preparation of the signalling device 102, in parallel with 5 to the reset button 101, and the signaling device 103, in parallel to each relative command button 104, allows the emission of relative signals, such as light signals. In particular, the signalling device signalling 103, which for example can be made by an LED mounted on the control button itself, it is automatically operated 10 if the relevant electrical load Z is powered by the relevant relay electromechanical 100. At the same time the signalling device 102, which can also be made for example by an LED mounted on the reset button itself, is automatically activated if any electrical load Z is powered. 15 By pressing the reset button 101 the corresponding seconds T2 control devices of relays 100 are powered only when the related monostable relay 11 assumes the operating configuration. In particular, if the monostable relay 11 assumes the configuration of rest, i.e. the first switch I1 is open, there is no closing of the 20 circuit from the second control device T2 to the reset button 101 activated and the current cannot flow through the second diode D2, as counter-polarized. In particular, if the monostable relay 11 assumes the configuration operational, i.e. the first switch I1 is closed, the reset button 101 25 operated allows the power supply of each relay 100, i.e. of each second control device T2 thus commanding its de-powering from the power source A of each electrical load Z. According to a preferred embodiment of the invention illustrated in Figure 4, the power system 30 is powered by a first source 5 power supply A1 and from a second power source A2 operating at a first voltage V1 and a second voltage V2 mutually. Preferably, each first control device T1 of the relative monostable relay 11, each second switch I2 of the related relay 100, each electrical load Z and each third diode D3 10 operate at the first operating voltage V1 and are powered by the first Power source A1. Operation follows as described previously, in particular the circuit powered by the source of Power supply A2 acts as a purely control circuit powered by power source A1, which powers the 15 relative load Z connected to the respective electromechanical relay 100.
