HYT5 Electric Spring Mechanism

HYT5 Electric Spring Mechanism

The HYT5 spring operating mechanism can be used for ZF3A-126、ZF4A-126、ZF10-126、ZF12-126、ZF1-252、ZF11-252 as well as isolating switch, grounding switch and load switch which have the same required torque.

The mechanism use the positive and negative turn functions of the motor by principle of spring symmetry so that the mechanism compression spring can achieve rapid operation with manual and electric functions.
