Use logical control board, with various logic, to manage the operational manipulation of the motor and gearbox mounted inside the switch so as to ensure the switch position.
The motor is of neoprene insulating damp-heat type with safety device, and it will trip off at the temperature of more than 110? and under the condition of over-current. It will work automatically after the fault is gone. Reversible reduction gear is made with straight-wheel teeth.
Good security
Zero flashover is basically realized(without arc-distingu-isher) by adopting double composite contact, transversal-connected structure, micro-motor pre-energy-storage and microelectronic control technology;
Adopt reliable mechanical interlock and electrical interlock technology;
Adopt zero-crossing technology;
Have obvious on-off position indication and padlock functions, which can realize reliably the isolation of power and load;
High reliability with the service life of more than 8000 times;
Electromechanical integrated design, making the switch transferred correctly, flexibly and reliably;
Good electromagnetic compatibility, strong anti-interference ability without interference to outside, and high automation level
The full-automatic type doesn't need connecting externally any control omponents
Smart appearance, small volume and small weight.

Electromechanical integration design, real ATS elements, DMC ( reinforced glass fiber) casing, high strength, high flame retardance and impact resistance.
Dual in-line double breakpoint, long break distance with reliable isolation function; integration design of main contact and arcing contact with zero flashover basically.
Use generator energy storage to accelerate, coaxial different-angle pull-rod mechanism with reliable
mechanical 0 position ( line I, II switch off simultaneously ), the operation mode is I-0-II, I-0-II.
High-speed transfer, without any external lines can it realize switch's full-automation, remote and manual functions; PC communication port is available.
It is widely used for the transfer between power supply system ( power supply for more than 2 lines or generator transfer) and fire protection system for more than 2 lines
