Sea-Dog 420201-1
Non-illuminated Contura rocker for a two-terminal on/off connection.
Sea-Dog Contura Rockers vs Standard Illuminated Rockers
Sea-Dog Contura rockers provide a broad, easy-to-press switch surface with marine-rated front-panel protection. The standard and illuminated Contura variants have different terminals for SPST, SPDT and DPDT circuits. The separate 420251 illuminated rocker uses a wider slot and a 15A rating, unlike the 20A Contura models.

| MPN | Action | Terminals | Rating | Manufacturer A × B |
|---|---|---|---|---|
| 420201-1 | Maintained SPST on/off | 2 blades | 20 A / 12V DC | 13/16 × 1-7/16 in |
| 420211-1 | Maintained SPST on/off | 3 blades | 20 A / 12V DC | 13/16 × 1-7/16 in |
| 420213-1 | Maintained SPDT on/off/on | 4 blades | 20 A / 12V DC | 13/16 × 1-7/16 in |
| 420218-1 | Maintained DPDT on/off/on | 7 blades | 20 A / 12V DC | 13/16 × 1-7/16 in |

Before selecting a replacement: The 420251 illuminated rocker is not a Contura switch. Contura models 420201/211/213/218 have manufacturer dimensions A = 13/16 inch and B = 1-7/16 inch; 420251 requires a 7/8 × 1-7/16-inch panel slot. The IP66 description for Contura applies to front-panel components only.
What to check before ordering
- Check that the original is actually a Contura rather than the separate 420251 rocker.
- Match maintained action and the number of controlled poles, not simply the front rocker colour.
- Count rear blades carefully: two, three, four, seven or three depending on the exact model.
- Compare the manufacturer's A/B panel measurements and the original switch opening before cutting the dash.
- Check that the circuit is suitable for 12V DC and that the load does not exceed the model's current rating.
