FIELD: electricity.
SUBSTANCE: in addition, electromagnetic drive includes the first and the second resistors and switch with one normally closed and one normally open contact. At that, the first resistor is in-series connected to normally closed contact, and the second resistor is in-series connected to normally open contact of switch; resistors are in-series connected to control coil.
EFFECT: eliminating the influence of voltage drop of power supply on the required operating procedure of electric equipment during the operation.
