Product Detail

Switch Structure

1.Electrical lock: control switch internal circuit power. when it is on, the switch can realize full-.automatic, forced recovery and remote operation; when it is off, the switch only can be manual operate.

2.Operation handle: The electrical lock should be off when the handle is used for manual operation.

3.Mechanism lock: using for detection. Firstly, turn switch to "0" position by using handle,then, pull the lock mechanism up and lock it, then taking detection.(pull up the lock, and the switch internal control power supply would be cut off, the switch can not automatic and manual operation.)

4.Position indication: indicate the working position(Ⅰ,O,Ⅱ).

Usage Method

Switch Function

1.Automatic function: when normal power supply is of, the switch transfers the circuit to Backup power supply; when normal power supply is recovery,the switch would transfer circuit to Normal power supply.

2.Forced recovery "0" function: start "0" button, the switch would cut two power supplies.

3.Remote control function: remote control, push "Ⅰ" button to start the normal power supply, Push "Ⅱ" button to start back up power supply; Push "0"button to cut off two power supplies.

4.Please choose the switch function,and connect according to needs.

5.Please mention the model No..Specification and needed functions.
