.~ Casing or housing formed on and hardened on resistor (e.g., molded)
DEFINITION
Classification: 338/275
(under subclass 226) Subject matter wherein the casing or housing has been applied to all or part of the remaining resistance structure in a plastic and formable state with substantially no intervening space between the casing or housing and the resistance structure, and then hardened in position.
(1) Note. Usually there is some bonding or adhesion between the casing or housing and the resistance structure which the casing covers. The most common examples of the subject matter of this class are plastic or ceramic casings molded on the resistor, or glass fused to the resistor. The hardening need not be sufficient to render the casing entirely rigid for classification in this subclass.

193, for mechanically variable resistors with an angularly movable contact, with an enclosure formed on and hardened on the resistance element.
210+, for flexible or folded resistors.
230, for resistors having a metal casing or housing cast around the element.
250, and 333, for resistors whose element is in insulation with an outer metallic sheath, the insulation being formed and hardened in situ, e.g., molded. 252, for resistors embedded or enclosed in a groove or recess with a filling hardened in situ.
262+, for resistors whose casing or housing is formed as a coating. See also (1) Note under subclass 262 for the distinction between a coating and the subject matter of this subclass (275).
269, for helical or wound resistors whose casing is formed on and hardened on the resistor, e.g., molded.
