.~ With electromagnetic operator (e.g., electric motor)
DEFINITION
Classification: 338/116
(under subclass 68) Subject matter including an electromechanical transducer such as a electric motor or a
magnetic relay, the moving part such as the armature of the transducer being mechanically linked with a mechanically moving operating part of the resistor.
SEE OR SEARCH THIS CLASS, SUBCLASS:
12+, for a resistor actuated by a movable magnet through a housing or partition.
32, for a resistor whose resistance value is responsive to a magnetic field.
36+, for resistors which are fluid or gas pressure actuated, and including variable resistors operated by fluid motors.
98, for a mechanically variable resistor with a motion dampening means such as a dashpot. 103+, for a pile type compressible resistor with an electromagnetic operator; and subclass 107 for such resistors with an electromagnetic holder.
189, for a mechanically variable resistor of the tap type including a magnetic holder.
