Hello Friends,

As a weekend project decided to try making a hdd grinder from old hdd motors.
I have managed to procure a 20 AMP ESC & a CCPM servo controller.
With just some basic knowledge got the motor running.

But have no idea designing a circuit.

My problem is how do i connect the supply from the ESC and design a circuit to control anyone of the 3 motors installed in the setup??
Do i need a simple toggle switch or a 3 way switch with a circuit??
Or something like a rotary cam switch??

Some learned people can guide me.

Thanks in advance.
