Another way to do tail e-switch?

What about a flat-flex wire ran in the tube which folds over both ends of the tube and makes contact with the driver and tail. Then make a new SW board so the current flows through the tail cap threads while the bottom of the switch board (which traditionally makes GND contact to the body) interfaces with the flat-flex cable for the switch signal?

I see that such wires are easily available, for example 24AWG sized 0.13*2.03mm.
Would you just glue it to the tube and remove the insulation at the ends? I can see it working in a mod but production might have problems with shorts…
Also, I wonder about abrasion, especially at the contacts. As you twist the tailcap there would be tail board rubbing against the wire.

I’ve thought about this a lot, I tried to make an anduril driver for a manufacturer that was powered by bleed resistor but the problem with that is you have to slow the pwm frequency down to the hundreds of hz range in order to provide enough power to the driver (+ flows threw body only between pulses) so while that did work, and I do have a 18650s that runs anduril, it’s not commercially viable because of the horrid PWM.

Ouch. Any idea why is it so? Folomov is fine with 17.8 kHz.
