DC Symbol ⎓

DC Symbol uses ⎓, the Unicode character U+2393 DIRECT CURRENT SYMBOL FORM TWO. Its design combines a solid line over a dashed line and is used in text or equipment-related notation to indicate direct current. The symbol should be read together with the voltage, polarity, port, or specification it labels. Examples include “Output: 12 V ⎓”, “DC supply ⎓”, “Direct-current port ⎓”, and “Power label: ⎓”. These forms show that ⎓ identifies the current type; it does not state the voltage or polarity by itself. A complete label may require additional values and safety information. Do not substitute the tilde ~, which is often associated with alternating current, and do not treat ⎓ as a circuit diagram. Equipment markings and regulated documents may require approved graphics or a particular technical standard, so a Unicode text character is not automatically sufficient for compliance. Add the words “direct current” when the audience may not know the sign. Test the final font because the dashed lower line may render poorly at small sizes. DC Symbol provides a selectable character for references and labels; electrical design, connection details, and safety instructions must remain in the applicable specification. Before using ⎓ on a product page or diagram, compare the label with the source specification. Confirm the voltage, polarity, and applicable connector, and do not infer safety information from the symbol alone. If a fallback font blurs the dashed line, pair the character with “DC” or “direct current” so the meaning survives visual degradation.
