Sierra RK19850TP Contura III Marine Rocker Switch – (On)-Off-(On), DPDT, IP68, Ignition Protected
The Sierra RK19850TP is a heavy-duty waterproof marine rocker switch from the Contura III series, built for demanding helm and marine electrical panel applications where ignition protection is required. The (On)-Off-(On) DPDT configuration provides momentary contact on both active positions — both sides spring back to center-off when released — while simultaneously switching two separate circuits. This dual-pole momentary action makes it ideal for trim tab control, windlass operation, and other dual-direction, dual-circuit momentary functions.
Rated to UL 1500 and ISO 8846 ignition protection standards, this switch is safe for use in areas where fuel vapors may be present — a critical requirement for switches mounted near engine compartments or fuel systems. IP66/68 sealing protects against dust and prolonged water spray. The switch includes both gray and black removable actuators, giving you flexibility to match your panel color scheme without ordering additional parts. Brass blade terminals with silver contacts ensure reliable, corrosion-resistant connections, and the neoprene mounting gasket is included for a watertight panel installation.

Parts Desk Insights
The RK19850TP is the right choice when you need a momentary DPDT rocker that is ignition-protection rated — the UL 1500/ISO 8846 compliance makes it the correct fit for any switch location near fuel vapors, engine compartments, or fuel system components where a non-ignition-protected switch would be a safety risk. The dual actuator inclusion (gray and black) is a practical bonus for panel builders who want color flexibility without sourcing additional parts. If you need the same (On)-Off-(On) momentary action but only need to switch a single circuit (SPDT), the Sierra RK19060 Contura XIV (On)-Off-(On) SPDT is the single-pole alternative. For a maintained (latching) DPDT On-Off-On switch, the Sierra RK19110 Contura XIV (On)-Off-(On) DPDT covers that configuration in the Contura XIV series.
