Trampa 100/250 switch operation without anti-spark idea

I have a Trampa 100/250 VESC and it recommends in its wiring an anti-spark switch.

These seem rather hard (i.e., impossible) to come by for 100V and any amperage that I’ve found.

I have the idea to use a latching power button to wake/sleep the VESC using the power button


I will include an external port for an anti-spark XT90 loop on the outside for long shutdown, safety cutoff and precharge (and fool/thief proof) startup.
That seems to me to get me away from needing an unavailable but otherwise expensive, heat generating, and space taking anti-spark switch.

The downside I had before was that it wont have simple switch operation, but here, in fact, it will.

I’d appreciate any one lending their evaluation of this logic.

This is the route I’m taking for my little focer build. I am replacing the charge port with an XT90E-M. The female XT90S just barely fits through the hole in the rail. I’m setting the E-M back into the control box and adding a string to the S so I can pull it out. Seems like it will work pretty well.

I can’t speak to how effective it is compared to a true antispark switch though. I know other people operate this way though.

Most of our VESCs are operated that way, I see no problem with that

I know this is late, but thanks.
