Sierra RK19050 Contura XIV Marine Rocker Switch – On-Off-On, SPDT
The Sierra RK19050 is a premium sealed marine rocker switch from the Contura XIV series — one of the most specified switch platforms in the marine industry for its combination of weatherproofing, reliability, and clean panel aesthetics. The On-Off-On SPDT configuration provides a center-off position with two independently selectable circuits, making it ideal for applications where you need to switch between two loads or directions from a single switch position.
Sealed to IP66/68 for above-panel components, the RK19050 keeps water and spray out of the switch mechanism even in the most demanding marine environments. The silver-plated butt contact mechanism delivers maximum contact reliability over thousands of cycles, and the greaseless construction handles extreme temperature ranges without maintenance. The removable actuator allows you to change the switch style or replace a worn actuator without removing the switch body from the panel.

Parts Desk Insights
The RK19050 is the right choice when you need a center-off rocker that can select between two circuits — common for trim tabs, dual bilge pumps, or any application where you want to energize one of two loads independently with a clear off position in the middle. The Contura XIV series is a strong choice for any helm panel build or refit where IP66/68 sealing and long-term contact reliability matter. For a simple On-Off (SPST) switch in the same Contura XIV series, the Sierra RK19000 On-Off SPST or Sierra RK19020 On-Off SPST are the single-circuit alternatives. For a momentary On-Off (spring-return) version, the Sierra RK19010 (ON)-Off SPST covers that application. For a dual-pole On-Off switch, the Sierra RK19070 On-Off DPST is available. The closely related Sierra RK19040 On-Off-On SPDT shares the same circuit configuration — verify the actuator style against your panel requirements when choosing between the two.
