What Is the Slash in Morse Code?
The Morse code for the slash (/) is -..-. — a sequence of 5 signals: dash, dot, dot, dash, dot. The slash (/) separates parts of a callsign or fraction. In Morse it’s five signals: dash dot dot dash dot.
When you search for “slash in morse code”, “morse code for slash”, “/ in morse code”, or “morse code /”, the answer is the same ITU-standard pattern: -..-.. Other common names for this character include forward slash, fraction bar, stroke.
When to Use the Slash
Separating prefixes/suffixes in ham-radio callsigns (e.g., "W1AW/7") and dates. In high-speed CW conversation, operators often skip non-essential punctuation — but for clarity, accuracy and written transcripts, the slash stays as -..-..

ITU Timing Rules
- Dot (·) = 1 unit
- Dash (−) = 3 units (3× longer)
- Signal gap = 1 unit
- Letter gap = 3 units
- Word gap = 7 units
Timing Reference Table
| Speed | Dot | Dash | Letter gap | Word gap |
|---|---|---|---|---|
| 5 wpm | 240ms | 720ms | 720ms | 1680ms |

How to Remember the Slash in Morse Code
Dash-dot-dot-dash-dot — sounds like “DN” run together. Five signals, easy and quick.
Frequently Asked Questions — Slash in Morse Code
The slash (/) in Morse code is -..-. (3 dots, 2 dashes). It’s the standard ITU code used worldwide.
The Morse code for the slash is -..-.. Tap the sequence as: dash, dot, dot, dash, dot, with a one-unit gap between each signal.
To send the slash: long press, then short tap, then short tap, then long press, then short tap. Keep one unit of silence between each signal and three units between this character and the next.
The slash uses 5 signals total: 3 dots and 2 dashes. Most punctuation marks in ITU Morse use 5 or 6 signals.
Separating prefixes/suffixes in ham-radio callsigns (e.g., "W1AW/7") and dates. Punctuation is optional in casual CW, but standard for formal messages and written transcripts.
Yes — -..-. is defined by the ITU (International Telecommunication Union) Recommendation M.1677 and is used worldwide for the slash.
