6.5 Definitions. For the purposes of this specification, the definitions
specified in 6.5.1 through 6.5.9.8 shall apply.
6.5.1 Switchboard. A switchboard is a device which contains such items
as switch assemblies, panel assemblies, switches, fuses, monitoring instruments,
terminal boards, and wiring with associated framework and enclosure and which is
used specifically to energize, switch, protect, and coordinate shipboard control
circuits or equipment. A switchboard may consist of one or more sections.
6.5.2 Switchboard section. A switchboard section is a self-contained
structure composed of a front section and a back section. The front section
consists of a complete framework on which are mounted panels containing equip-
ment such as switch assemblies, indicator lights, fuses, relays, and other items
as required for energizing, protecting, connecting and coordinating shipboard
control circuits or equipment. The panels may be mounted on a hinged door with
the connections to the back section made by connectors to the flexible wiring
harness. The back section may be separable (for example, attached by bolts)
from the front section or it may be a completely separate section. The back
section consists of a complete framework on which are mounted modules con-
taining terminal boards or connectors for connecting to ship wiring and con-
nectors for connecting to the front section harness wiring.
6.5.2.1 Door. A door is a framework supporting an assembly of switches,
indicator lights, relays, and other items that make up a switching system.
Its components are connected to ship wiring by means of flexible wiring harness
to the back section modules.
6.5.3 Switch assembly. A switch assembly is a mechanical grouping of one
or more switches associated with accessories, such as remote operating mechanism,
wiring, connectors, fuses, and indicator lights. The components may be fixed or
joined into an assembly which may be removed readily as a unit from the parent
switchboard.
6.5.4 Panel assembly. A panel assembly is a mechanical grouping of one
or more components fixed or joined into a unit that may be readily removed from
the parent switchboard. See MIL-STD-1657 for a description of the types of
panel assemblies used.
6.5.5 Control indicator. A control indicator is an item which performs
the essential, dual function of presenting visual information from, and regu-
lating the mode of operation of, another equipment.
6.5.6 Set-up control system. A set-up control system is one which permits
the operator to effect any predetermined control switching pattern with one
operation, such as pushing a button.
6.5.7 Switch, programming. A programming switch is a remote operated
switch which is positioned by a pushbutton or switch from a remote station and
which in turn operates other remote operated switch assemblies throughout the
ship to establish a predetermined control switching pattern. Programming
switches may be incorporated in switchboards or control indicators.
