Team 241 uses a high friction hinged flap over the top of the kit-of-parts limit switch. When the hinged flap hits the plate, it absorbs the energy in the friction on the hinge. The bottom of the flap then strikes the limit switch and the minibot starts down the pole in brake mode. The small spring in the limit switch is not strong enough to push the high friction hinged flap up. After the minibot comes down you manually have to put the flap back up and off the limit switch to be ready for the next race.

Our hinged flap is just a piece of angled aluminum connected to the minibot with a screw and TWO nuts as the hinge. The first nut is tightened until the hinge gives the right amount of friction, the second nut is tightened while securely holding the first nut in place. This will keep it from loosening.
The flap can also have a stop under it to assure the limit switch does not absorb the full blow of the tower plate. The stop can just be a well placed screw and nut.
