is my wiring good?

I recommend using a switch that locks in the open position when the bot hits the top. In our testing, limit switches on the top that didn't lock cause issues when taking the bot down. As soon as it starts to slide down, the switch is back in the initial position and will climb the pole again, then repeat. You can make an apparatus to keep the switch in the NO position when it hits, but a push button type of switch is the easiest and (should be) the most reliable.
