FIELD: electrical engineering.
SUBSTANCE: proposed forced electromagnetic drive incorporating built-in rectifiers that may be found useful in various computerized and automatic-control systems, and switching devices supplied with power from variable-polarity voltage source has power terminals, single-phase bridge rectifiers, two electromagnetic-drive coils connected across diagonally opposite output terminals of single-phase bridge rectifiers, forcing contacts, and circuit set up of series-connected ballast capacitor and current-limiting resistor. Output terminals of bridge rectifiers are connected in pairs to forcing contacts and to power terminals, respectively, and RC circuit is connected to terminals of forcing contacts which are not directly connected to power terminals.
EFFECT: reduced mass and size.
