DEFINITION

Classification: 338/194

(under subclass 185) Subject matter wherein the contact moves in a straight line over the conducting structures connected to the resistance element.

SEE OR SEARCH THIS CLASS, SUBCLASS:

74, for a mechanically variable resistor having a rectilinearly slidable contact in or on a lamp socket.

133, for ganged plural resistors operated rectilinearly.

176+, for mechanically adjustable resistors including a contact rectilinearly slidable on a resistance element.

190+, for resistor with an intervening connector between the contact and element, the contact being angularly movable.

SEE OR SEARCH CLASS 200, Electricity: Circuit Makers and Breakers,

4, and 16, for multiple circuit control switches with a reciprocating contact; and subclasses 76+ for snap switches having a reciprocating contact.
