Sierra RK19550-1 Contura Marine Rocker Switch – (On)-Off-(On), DPDT, Momentary Both Sides, Illuminated, 7-Terminal
The Sierra RK19550-1 is an illuminated marine rocker switch with a (On)-Off-(On) DPDT (Dual Pole, Double Throw) configuration where both active positions are momentary. The switch springs back to center-off the instant you release it in either direction, while simultaneously switching two independent circuits. This makes it the correct choice for dual-circuit momentary control applications such as trim tabs, reversing actuators, and windlasses where you need to switch polarity or route two circuits simultaneously and want the action to stop the instant you let go.
The DPDT configuration uses 7 blade terminals — three per pole plus one shared common — providing the wiring points needed for full dual-circuit momentary reversing control. The switch illuminates when in an active on position, giving visual confirmation that the circuit is energized. Black actuator with non-corrosive plastic construction. Brass blade terminals with silver contacts ensure reliable, corrosion-resistant connections. Rated at 20A at 12V DC. The removable actuator allows style changes or replacement without removing the switch body from the panel.

- Marine helm panels requiring illuminated momentary DPDT rocker switches
Parts Desk Insights
The RK19550-1 is the right choice when you need to switch two circuits simultaneously in a momentary format — the DPDT configuration is the standard wiring approach for reversing motor circuits (trim tabs, actuators) where you need to swap polarity on both the positive and negative leads at the same time, and the momentary action ensures the motor stops the instant you release the switch. The illuminated on-indicator confirms which direction is active while you’re pressing. The 7-terminal blade configuration provides all the wiring points needed for a complete reversing circuit without additional relays in many applications. For a non-illuminated DPDT On-Off-On maintained switch in the same Contura series, the Sierra RK19480-1 Contura Non-Illuminated may cover a maintained dual-pole application. For a single-pole momentary (On)-Off-(On) SPDT switch in the compact series, the Sierra RK40870 Compact (On)-Off-(On) SPDT is the single-pole compact alternative.
