DEFINITION

Classification: 338/177

(under subclass 176) Subject matter wherein the rectilinearly slidable contact completely surrounds or embraces the resistance element, and contacting the element around the entire periphery of the element.

(1) Note. Subject matter generally found in this subclass consists of an elongated resistance element having a rectilinearly movable conducting band or ring completely encircling the element to form a contact having ringed engagement entirely around the resistance element.

SEE OR SEARCH THIS CLASS, SUBCLASS:

92+, for variable resistors having a short circuiting means which may include a conducting contact completely surrounding the resistance element.

272, for incased resistors whose terminals or leads surrounds and are secured to the casing or housing.

313, for resistors with elements extending along a base, the terminals surrounding the base. 332, for resistors with terminals embracing or surrounding a resistance element.
