But it actually works by supplying power to the motor as long as it's NOT retracted. So even if you let go of the trigger, the sensor supplies power to the pusher until it cycles back to its retracted state, then cuts out.

The problem is I upgraded the pusher motor and it goes a lot faster. The momentum of the motor continues to turn the pusher gears for a fraction of a second after I let go of the trigger. Just enough to move the pusher away from the sensor switch, which then starts supplying power to the motor and makes the pusher cycle again. It's basically an endless loop.

To make the pusher motor stop instantly, I'm working on a motor brake. Hasbro was kind enough to use Double Pole Double Throw switches in the RapidStrike. They are able to control two separate circuits at the same time. One set of poles currently controls the supply to the motors. I'm going to use the other set of poles to short out the motor contacts, which will bring it to a screeching halt. Hopefully.
