Sea-Dog 4204271 Momentary Push-Button Switch 30A @ 12VDC

A high-current momentary push-button switch engineered for marine environments.

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.
