Diy anti spark switch?

[kook]

• 1. I measured the resistance in a cheep multimeter of an existing XT90S as 5.6 ohms
• 2. in your drawing you show a 3 pole switch, if the switch is left in position 2 for more than a moment the resistor will blow
• 3. The switch you linked is a SPST switch

How to make an XT90 Loop Key

Arguably, the most reliable way to control power to an ESC [pair] is to use an XT90S loopkey. [20190219_024916][20190219_024931] It may not be the prettiest or the shiniest or the most foolproof, but it probably will outlast almost any other way if done correctly, and it’s certainly the cheapest. This does have antispark characteristics if you use the “XT90S” instead of the “XT90” variant of the female connector. You definitely don’t want to use the female XT90. Essentially, you make “a k…
