Isolator switch: A switching device, mainly used for "isolation power, switching operation, to connect and cut off the small current circuit", no arc function. Isolation switch, that is, in the sub-position, the contact between the requirements of the insulation distance and clear off the mark; in the joint position, can carry the normal circuit conditions and the current conditions within the specified conditions.

Disconnector (commonly known as "knife gate"), generally refers to the high-voltage isolation switch, that is, rated voltage above 1kV isolation switch, usually referred to as the isolation switch, is the most used in high-voltage switch electrical appliances. Its own work principle and structure is relatively simple, but due to the use of large, high reliability requirements, the substation, power plant design, establishment and safe operation are greater impact. Is the main feature of the disconnector is no arc suppression capability, only in the absence of load current in the case of sub-combined circuit.

Disconnector is used for all levels of voltage, used to change the circuit connection or the line or equipment and power supply isolation, it is no drying capacity, can only use other equipment to disconnect the line after the operation. In general, interlocks are provided with an erroneous operation to prevent the switch from being overloaded, and pins are sometimes required to prevent the switch from breaking off under large magnetic forces.
