FIELD: automatic circuit-switching equipment. SUBSTANCE: switching device monostable polarized relay 2, capacitor 3, diode 4, transistor 5, and resistor 6 is provided with voltage regulator diode 7 connected in parallel with capacitor 3; diode 4 and voltage regulator diode 7 are interconnected by like-polarity leads. EFFECT: reduced loss across resistor during relay opening and provision for using relay at preset pull-in voltage and various resistances of winding without readjustment of resistor. 1 dwg
