After messing with heavy light switches, Team 241 decided on limit switches.
Creating a simple high friction hinge over the top of a KOP 3-way limit switch is a lightweight and effective way to short the motors when you reach the top- the friction in the hinge keeps the limit switch from turning back on.
A high friction hinge can be as simple as a small piece of angled aluminum with a machine screw that is double nutted to adjust compression/friction)
The KOP limit switch is very easy to mount to a vertical member of your minibot. Adding a travel stop on the hinge to protect the switch is also advisable.
If you have a super fast minibot, the hinge allows longer contact with the tower plate while in excess of 4N.
