Updated with the motor controller, push buttons and interconnects. Here's the latest video of the guard in action. I think I'll keep this as is while I get through a few more woodworking projects and then add the sliding mechanism. Will update the thread when that happens.
I used 5 pin aviation interconnects for both the motor and switch hookups for easy removal.
Wiring inside the dust guard assembly within one of the unused cavities:
19mm momentary push buttons mounted. I tried to incorporate Felder OE but they were just too bulky.??
The motor controller is the green module -- it takes an active high signal and provides simple forward / reverse control for DC motors in a very small package. It's made by Phoenix Contact.?
