What does patchboard mean?
A patchboard is a board or panel used to connect, disconnect, and redirect electrical or telecommunications circuits. Its connections are commonly made with flexible cords or cables that can be removed and placed in different sockets. The word is especially associated with older telephone exchanges, where operators could reroute calls by changing these connections; comparable boards were also used in electrical and telecommunications engineering. A patchboard differs from an ordinary wiring board because its connections are intended to be patchable rather than permanently fixed. The term now sounds dated to many listeners, who are more likely to encounter patch panel or patch bay in descriptions of modern audio, network, and data equipment. Nevertheless, it remains useful for understanding historical communications technology and for identifying boards whose connections were changed through removable cords rather than permanent rewiring.
nounA board or panel carrying connections that can be joined, disconnected, or rerouted by plugging flexible cords or cables into them. The term is now chiefly associated with historical telephone and telecommunications equipment.
- A board or panel on which circuits or connections can be joined, disconnected, or rerouted by plugging flexible cords or cables into them.
- Historically, a perforated board into which the ends of flexible tubes were inserted to route or distribute telecommunications connections.

Where does patchboard come from?
Patchboard is an English compound formed from patch and board. Patch has Middle English ancestry through Old French words meaning a piece, scrap, or cloth fragment, while board comes from Old English bord, originally referring to a plank or the side of a ship. Packet is a cognate that also developed through the older French material associated with patch.
How patchboard is actually used
This is specialized, largely historical vocabulary. In modern technical contexts, patch panel and patch bay are generally preferred, although patchboard survives in descriptions of older telephone and electrical systems.
Easily confused with patchboard
A patch panel specifically names the modern panel containing jacks for patching circuits, whereas patchboard is an older, broader term for the board or assembly used to hold such connections.
