Conclusion reset 31 of the memory block is connected to the first output capacitor 6. In parallel to the switch 11 with the latch pins can be connected to the same other control buttons 32 that are located in different spots of the room where you installed swimmy 2, 3 network via the capacitor 7, ballast resistor, such as resistor 18, and parallel counter is enabled diodes 12, 13 and the transition control electrode-cathode of the triac 5, the current flows. To the voltage drop across the resistor 18 through the diode 14 is charging the filter capacitor 6, which is the food of the memory block according to the conclusions of 26, 27. On launching the entrance 28 of the memory block 1 through the capacitor 19 and the resistor 9 receives the potential of the upper output capacitor 6, so the potential at the output 30 of the memory block approaches the potential at the output 27 of the memory block, i.e., the lower the output capacitor 6. Unlocked the transistor 17. Through this transistor 17 and resistor 23 current flows in the control circuit of the transistors 15 and 16 and they operas, continuum the control circuit of the triac 5. When the triac 5 is locked and the load 4 is disabled.

First pressing on the control button 11 (32) trigger input 28 of the memory block by connecting in parallel to the input and common output 27 through a capacitor 20, resistor 22 and the contacts 11 (28) short shunted. Since the resistance of the resistor 22 is several times less than the resistance of the resistor 9, the threshold input 29 of the memory block receives a voltage pulse lower 2/3 voltage Pete who are at the expense of short-term bypass its trigger input 28 of the condenser 20. Thus, the potential at the output 30 of the memory block approaches the potential of the upper output of the first capacitor 6. Therefore, the transistor 17 and, consequently, the transistors 15 and 16 are locked, and the control circuit of the triac 5 discontinued. Through the condenser 7, the resistor 18, the diodes 12, 13 and the control circuit of the triac 5 current flows, under which the triac is unlocked, and the load 4 will turn on. Memory block 1, and hence the triac 5 is held in this state and after disconnection of the control buttons 11(32). After opening the contacts 11 through resistor 24 charging the capacitor 21 to the potential at the output 30 of the memory block.

Pressing the button 11 or 32 and the closure of its contacts, the capacitor 21 through the opening of the diode 8 is discharged by the resistor 22. Under the action of the voltage pulse allocated to the resistor 22 and arriving at the threshold of the entrance 29 of the memory block and the memory block switch, the voltage at the output 30 of the block is reduced to the potential on the lower lead of the capacitor 6, the transistors 17, 15, 16 are opened, and the triac 5 and the load 4 are disabled. In further operation of the device is repeated.

Parallel counter is enabled diodes 12 and 13 provide a reliable bypass circuit control SIMEST is to be applied to the resistor parallel connected diode, shunt resistor when the plus potential at terminal 3, or a Zener diode. Diode 8 excludes the charge of the capacitor 21 through resistors 9 and 10 when the potential at the output 30 of the timer is equal to the potential at the output 27 and, therefore, provides a bypass trigger input 28 of the memory block at the time of the first closing contacts 11(32) buttons and turning on the triac 5 and the lighting device 4. The time constant of charge of the capacitor 20 through resistor 9 is less than the time constant of the discharge of capacitor 21 and resistor 22, which provides reliable switching of the memory block by repeatedly pressing the button 11(32).

Thus, this device is characterized by simplicity of the scheme, reliability and efficiency, since the entire power consumption is allocated in the control circuit of the triac. In this case, control of the lighting device can be accessed from multiple locations through a simple control buttons connected to circuit two-wire line.
