The new technology for Direct Debugging Switch(DDS) in electric actuators.

It completely solved the problem of complex debugging and make the technology simpler.

The debugging can be simplified from 5 steps to 1 step.

The debugging for electrical and mechanical position can be easy achieved through rotating the knob on the top of the dial after electric actuators and valves are assembled together.
