City power-oil machine automatic cut over schematic drawing

The logic control board will send out different logic commands to control the operation of the gear-motor directly assembled in the switch to ensure the position of the switch.

      The gear motor is made of neoprene to insulate wetness and heat,has a safety device. It will trip off whenth temperature is over 110℃ and when it is under over-current state,

where the trouble is disapperared,the device will automatically resumes its work,the reversible reduction gear adopts straight tooth gear.
