Switch Nut is a nut that can be right-handed or left-handed. The big nut has a little slider that is operated by pushing or gravity. In one state, the nut turns in a right-handed helix, in the other left-handed. Moreover, the nut cannot be placed upside-down. This is because of the asymmetric double threaded bolt, which was reused from Ambidextrous Safety Nut.
