(under the class definition) Subject matter including a mechanically variable resistor together with a partition, wall, or housing; and a movable magnet, usually permanent,
which when moved is effective by its field through the partition, wall, or housing to change the mechanical setting of the variable resistor and thus change the resistance value of the variable resistor.
(1) Note. Usually a second magnet is disposed on the opposite side of the partition, wall, or housing from the movable magnet, the second magnet being mechanically linked with the variable resistor and being adapted to be moved by the field of the first movable magnet.
