This is the generic class for devices, per se, of general application
which are used for closing or opening electrical circuits and the
combination of these devices with their operating means. In the
combined devices there must be something more than the mere inclusion
of a circuit maker or breaker broadly.
Combinations of circuit makers and breakers with electrical
plugs, sockets, or other connectors are in this class.
This class includes devices known as "controllers", "circuit-closers", "switches", "circuit-breakers", "interrupters", "distributers", "thermal-cut-offs", "fuses",
and "electrical thermostats".
Electrical systems or circuits are excluded from this class.
These systems or circuits are classified in the various electrical
or art classes, depending on the particular form of electrical system
or of the apparatus controlled.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
A circuit maker or breaker of this class (200) can be distinguished
from an electrical connector of Class 439, Electrical Connectors,
in that a circuit maker or breaker comprises an assemblage of parts
including both a movable contact and its mating contact wherein
there is a positive (permanent) physical connection between the contacts
such that a contact is restricted to move with respect to a mating
contact along a prescribed path each time the circuit maker or breaker
operates, whereas an electrical connector is physically separated
from the distinct, mating connector each time the circuit is broken.
The combination of an electrical circuit maker or breaker
with an electrical connector will be found in this class (200).
For example, an electrical connector with a distinct switch actuated
by a mating connector is included in this class (200), especially
in subclasses 61.58+. An electrical connector that includes
integrally therewith a "switching" component actuated
by coupling engagement with a mating connector is to be found in
Class 439. Search especially Class 439, subclass 188 for an electrical
connector having circuit interrupting provision effected by mating.
An electrical connector, per se, may include movable contacts
and be in the class of electrical connectors. For example, Search
Class 439, subclasses 43+ for an electrical connector with
a selectable circuit wherein no details of the circuit structure
is set forth; subclasses 152+ for an electrical connector
detachable from a mating connector by snap or quick-break action;
subclasses 259+ for a connector with a contact moved laterally
into engagement with a mating contact in a "zero insertion force
device"; subclasses 296+ for an electrical connector
with coupling movement-actuating means or retaining means in addition
to the contact, especially subclasses 310+ for a retaining
means with distinct movement-actuating means to move a coupling
part axially; and subclasses 374+ for an electrical connector with
guiding means for mating of a coupling part.
This class (200) has not been screened to verify placement
according to this line.
Search should be made in the art or special application classes
for circuit-controllers of such special type as to be peculiarly
adapted for those arts-- e.g., telegraph keys in Class 178, Telegraphy,
telephone-switches in Class 379, Telephonic Communications.

which are operated by the breaking of the wire to disconnect the
broken section.
This subclass is indented under the class definition. Devices in which the operating means is responsive to pressure
of a liquid, gas, or vapor. The pressure may be caused by a confined
fluid or by the flow of a fluid.
(1)
Note. This group includes devices responsive to vacuum.
Registers,
subclass 452 for record-sensing devices wherein a switch may be
opened or closed or circuits made in accordance with areas on the
record that contain coded indicia, the area where said indicia is
sensed conveying particular information.
Electricity: Electrothermally or Thermally Actuated
Switches,
subclasses 114+ for electrothermally operated switches employing
expansible or vaporizable fluid and subclasses 306+ for
similar thermally actuated switches.
This subclass is indented under subclass 81. Combinations, of two or more distinct circuit makers and
breakers, each having its own operating means, at least one of said
operating means being responsive to pressure of a fluid or to vacuum.
This subclass is indented under subclass 81. Devices, having two or more distinct operating means, at
least one of which is responsive to pressure of a fluid or to vacuum.
for combinations of two or more distinct circuit
makers and breakers, each having its own operating means, at least
one of said operating means being responsive to pressure of a fluid or
to vacuum.
Machine Element or Mechanism,
subclasses 625+ for gearing having provision for operation by either
manual or power means, and subclass 479.01 for manually operated
control lever and linkage systems having a plurality of controlling
elements.
This subclass is indented under subclass 81. Devices of the type in which the fluid pressure (or vacuum)
acts upon a body of conductive liquid causing the latter to move
so as to open or close a circuit including the conductive liquid.
(1)
Note. The fluid pressure or vacuum may be applied either
directly to the conductive liquid, or indirectly through a piston or
diaphragm, so that the change in pressure causes liquid motion,
as distinguished from fluid pressure operated means that cause change
in position of a liquid contact switch, liquid motion being due
to such change in position.
Electricity: Electrothermally or Thermally Actuated
Switches,
subclasses 122 and 331 for electrothermal or thermally actuated
switches with conductive fluid contacts.
This subclass is indented under subclass 81. Devices, of the type in which the operating means includes
a flexible, arc-shaped tube, the curvature of which changes in response
to changes in the fluid-pressure therein.
This subclass is indented under subclass 81. Devices of the type in which the operating means is responsive
to the flow of a fluid (including air-currents, wind, etc.), as
distinguished from those which are responsive merely to the static
pressure of the fluid.

Note. See alphabetical index to the classification of patents,
the title "Flow" for the distribution of flow
controlled devices in the several classes.
