VACUUM SWITCH Russian patent published in 2016 - IPC H01H33/66 

FIELD: electricity.

SUBSTANCE: invention relates to low-voltage and high-voltage electrical engineering and can be used in electrical circuits for remote control electric drives. Vacuum switch comprises insulating body, at least one vacuum arc-extinguishing chamber arranged in the cross beam connected via movable current lead and levers with electromagnet armature, disconnect springs, disconnecting electromagnet and rigidly mounted on levers stop element interacting with armature of disconnecting electromagnet. Stop element can be made in the form of a plate with projection, and the armature of disconnecting electromagnet can be equipped with a groove or ledge. Switch electromagnet coil power supply circuit can be added with tripping contact connected to the armature of disconnecting electromagnet.

EFFECT: technical result provides device operation in two fixed positions at closed and open contacts of vacuum arc-extinguishing chamber, as well as when deenergizing the electromagnet coil feed circuit.
