(under the class definition) Subject matter including an electrode or terminal, which may include the adjacent supporting structure such as the contact arm, the electrode or terminal being adapted to connect movably and electrically along or into a resistance element as by sliding along or into the element, the electrode or terminal as such not being otherwise classifiable.
(1) Note. For classification here the claims must be limited to the contact and arm, the resistance element being excluded. Subclasses 68+, and especially subclasses 118+, provides for the combination of the resistance element and contact movable thereon. Contacts which operate with taps electrically connected to a resistance element are classified elsewhere (see the Search Notes below)..

74, for a mechanically variable resistor having a rectilinearly slidable contactor and being incased in a lamp socket.
118+, for mechanically variable resistors including a contact movable over a resistance element. See also (1) Note above.
153, for a variable resistor with a movable contact operated by a pedal or treadle.
155, for a variable resistor with a contact that rocks along the resistance element. 156, for a variable resistor with a liquid contact movable over the resistance element.
157+, for a variable resistor with a contact that rolls along the resistance element.
