GROUP ELECTROMECHANICAL SWITCH Russian patent published in 2008 - IPC H01H19/62 

FIELD: electricity.

SUBSTANCE: invention relates to group electromechanical switch with angular displacement of control element and is designed to switch over startup-and-break resistors stages in principle circuits of electric drive. Switch is provided with contacts actuated in radial direction by directed cams and elements mounted on common shaft such as contacts actuator in the form of multi-type set of profiled cam rings, device of angular shaft position arranged as contact-free sensor of absolute angular position with electrical outputs connected with electric motor control unit inputs. Motor shaft is linked with switch shaft via coupling and gearing. Anchor windings and induction windings are connected with control unit outputs being in the form of electronic programmable unit of angular shaft displacement connected to motor anchor and induction windings via electronic switchboard unit ensuring programmable cyclic startup, shutdown, electrical braking and reversing of electric motor in angular shaft position function.

EFFECT: improvement of accuracy, increment, stability and fast action of switchover control, improvement of reliability and extension of operational life while reducing switch weight, dimensions and manpower effort during manufacture process.
