(under the class definition) Subject matter wherein the resistor has terminal structure which is readily detachable from the associated terminals, and which terminal structure constitutes the resistor mounting means, the resistor being readily separable as a unit from the associated terminals.
(1) Note. As all resistors must have some type terminal or connector in order to be connected in a circuit for use, it is necessary that the terminal structure be significant, as by being included in the patent claim. Usually the terminal structure constitutes parallel prongs or a screw plug. See also (2) Note under subclass 220 above.
