FIELD: remote control of illuminating devices. SUBSTANCE: when control button 11 or 32 is pressed and its contacts close, capacitor 21 is discharged to resistor 22 through diode 8. Voltage pulse from resistor 22 is received at threshold input 29 of memory unit. As result it switches. Voltage at output of memory unit 30 is decreased down to potential at lower terminal of capacitor 6. transistors 15, 16, 17 are rendered conductive and load 4 is disconnected. EFFECT: increased functional capabilities. 1 dwg, 1 tbl
