DEFINITION

Classification: 338/190

(under subclass 185) Subject matter wherein the contact moves angularly over the conducting structures connected to the resistance element i.e., the contact moves about a pivot point.

(1) Note. To be properly classified in this subclass the tapped resistance element need not have an angular shape nor do the taps need to be in an arcuate or circular configuration. The contact however must move about a pivot point in such a manner as to strike an arc of a circle when moved across the taps.

SEE OR SEARCH THIS CLASS, SUBCLASS:

162+, for resistors having an angularly slidable contactor which slides along and remains in contact with the resistor element.

194, for a variable tap type resistor having a slidable contactor which moves in a straight line.
