Sea-Dog 4204271 Momentary Push-Button Switch – 30A @ 12VDC
A high-current momentary push-button switch engineered for marine environments. The Sea-Dog 4204271 features a glass-reinforced polyester housing with an elastomeric rubber internal gasket and ultrasonic welding for superior water resistance — built to handle the moisture, vibration, and salt exposure common to helm panels and engine compartments. Its compact behind-dash profile makes it easy to fit in tight panel cutouts without sacrificing performance.

Parts Desk Insights
Best use case: The Sea-Dog 4204271 is the right choice when you need a high-current momentary switch for engine start buttons, trim tab controls, windlass jogging, or any application requiring a brief burst of current rather than a latched on/off state. The 30A rating gives it headroom for starter circuits and high-draw accessories, while the ultrasonic-welded housing makes it a reliable fit for exposed or semi-exposed panel locations. For a lower-current momentary option in the Cole Hersee line, see the Cole Hersee M485BP Momentary Push-Button Switch (10A) or the Cole Hersee M639BX Momentary Off Push-Button Switch. For a heavy-duty 35A push-button, see the Cole Hersee 90030BP Heavy-Duty Push-Button Switch. For Sea-Dog kill switch options, see the Sea-Dog Safety Ignition Kill Switch.
