DEFINITION

Classification: 200/51

(under the class definition) Connector coupling devices (a) combined with a switch in a unitary structure, or (b) capable of functioning as a switch; i.e., having means specially provided for holding the complementary coupling parts in mechanically coupled but open-circuit position. (For exceptions, see especially Note (4) below).

(1) Note. "Connector coupling" as used above refers to electrical connectors, other than mere binding posts, comprising a pair of complementary parts each having contact means adapted to be readily engaged or disengaged by manipulation of said parts. Such parts are commonly known as plugs, sockets, receptacles, and the like.

(2) Note. For the distinction between "connectors" and "switches", see Note (3) to the main class definition.

(3) Note. The plug, socket, et cetera, may constitute or be combined with the base of a lamp, heater, or other translating device and mere recitation by name only of the lamp, heater, or such other device does not exclude the patent from this class.

(4) Note. Combinations of connector-coupling devices with the following specified types of circuit makers and breakers are excluded from this subclass and will be found in the subclasses indicated below in Search This Class, Subclass.
