Mechanism output angle: about 88°

Mechanical life: 1000 times.

Operating specification

O Energy storage operation

Confirm the inspection of the product for transport deformation,fix the mechanism to the switch and insert it into the lower right part of the mechanism with a dedicated operating handle. Rotate clockwise (or charge the motor) till cracking sound occurs, which indicates the finish of energy storage

O Closing operation

Press the green button,and the breaker switch is closed by the spring force of the mechanism.Or when the motor is operated, the closing operation of the closing coil charging mechanism is completed, and the opening spring is stored. At this time, the energy can be stored again but cannot be closed again (with interlock).

O Opening operation

Press the red button,and the breaker switch is opened by the spring force of the mechanism.Or when the motor is operated, the opening operation of the opening coil charging mechanism is completed
