DEFINITION

Classification: 338/192

(under subclass 190) Subject matter wherein the resistance element is enclosed or housed as defined in subclass 226 below.

(1) Note. Usually in this subclass the taps from the resistance element and the movable contact structure are located outside of the housing or enclosure surrounding the resistor element. For substantially completely housed tap type resistors whose contact arms are also enclosed or housed see subclass 184 above and 199 below.

64+, for resistors with electrical shielding.

70+, for mechanically variable resistors housed in a lamp socket.

80+, for mechanically variable liquid resistors.

161, for an incased variable resistance element with the casing partly removed to form a track for a movable contact.

184, for variable movable contact type resistors having a housing.

199, for variable resistors generally with a housing.

219, for fixed resistors housed in a lamp socket or base.

226+, for fixed resistors which are incased, embedded, or housed.
