Pretty much all of the limit switches listed on Amazon are the same poor quality switches. The roller cage is badly made so the j2 tension ring misses the wheel altogether in my build. I’ve ordered some Omron switches from Mouser in hopes that they will be better. Much more expensive but it seems a shame to build such a nice robot and have flakey limit switches.

Thank you for the feedback. I havnt seen the issue with the tension ring but I will look at that. Let me know what you think of the Omron swtiches, im interested to know how the quality and fit is.
Top is cheap from Amazon; bottom is Omron from Mouser.
Left is cheap; right is Omron.
