DEFINITION

Classification: 338/107

(under subclass 101) Subject matter including a retaining or positioning magnet for locking or holding the pressure

controlling means in a predetermined position.

SEE OR SEARCH THIS CLASS, SUBCLASS:

12+, for resistors wherein a movable magnet actuates the resistor through a housing or partition.

103+, for compressible pile type resistors whose pressure controlling means are actuated by an electromagnet.

189, for tap type variable resistors including a magnetic holder for the controller arm.
