The 3shul Vesc pin 24 states:
“Ignition Input. Connect to + Rail of controller to turn on the controller. (126 V max)” and seemingly won’t go on without using it.
Can I add one of these two switches?
One has three wires and one has four. The three-wire switch has:
“LED : 8
25-48v” written on it
“Best” doesn’t mean anything. Best for what? Reliability? Appearance? Cost? Svelte? Ego? UX? Speed of manufacture? Best switch that doubles as a spearmint growing container?
If reliability is your goal, then use a 15Ω QS8 loopkey epoxied through the enclosure on the power rail, and connect the IGNITION wire straight to ESC+.
