FIELD: electricity.
SUBSTANCE: invention relates to controlling an electrical switch having two breakers, such as an earthing disconnector and a bus disconnector. According to the invention, the switch includes a common actuator (22) for movable contacts of breakers, which is designed to open one of the breakers while leaving the other closed and vice-versa. In the mechanism, the shape, size and arrangement of movable contacts (200, 210) and actuators thereof (22, 220, 221, 2210, 2211, 2220, 2221, 222, 223) enable the movable contacts to cross on rectilinear paths.
EFFECT: high compactness, manufacturability, reliability and safe operation of the switch owing to low lateral forces acting on movable contacts of the device.
