Open-circuit-output L-type Symbol
⎐ is a technical Unicode character used to depict an open-circuit output of an L-type in engineering diagrams.
U+2390
⎐ (Unicode U+2390) is a technical symbol used in schematic-style notation. It represents an open-circuit output using an L-type form. Use it in documents where you want a compact, standard character instead of an image.
Open-circuit-output L-type Symbol Symbol Meaning
⎐ is named “OPEN-CIRCUIT-OUTPUT L-TYPE SYMBOL” (Unicode U+2390). It is primarily a technical, diagrammatic glyph rather than a widely recognized cultural or everyday symbol. In schematics and engineering documentation, such symbols commonly indicate a specific connection state—here described as an open-circuit output—with an L-type arrangement. Because the character is defined in the Unicode Technical & Computer category, its exact interpretation depends on the diagram conventions of the system you are using (for example, electronic or signaling notation).
Common uses
- •Annotating circuit diagrams in text where a schematic glyph is needed
- •Labeling ports or output states in engineering documentation
- •Replacing small inline icons in technical PDFs, slides, and reports
- •Marking open-output conditions in specification drafts
- •Using as a lightweight visual cue in UI mockups for engineering tools
