Sierra RK19890TP Contura III Marine Rocker Switch – On/Off, SPST, Illuminated, IP68, Ignition Protected
The Sierra RK19890TP is a heavy-duty illuminated marine rocker switch from the Contura III series, combining ignition protection certification with IP66/68 waterproof sealing and a clean On/Off SPST single-circuit configuration. Rated to UL 1500 and ISO 8846 ignition protection standards, it is safe for use in areas where fuel vapors may be present — making it the correct choice for switches mounted near engine compartments, fuel systems, or any location where ignition protection is a code or safety requirement.
The illuminated actuator provides clear on/off status visibility in low-light conditions. Brass blade terminals with silver contacts ensure reliable, corrosion-resistant connections. Both gray and black removable actuators are included, giving you flexibility to match your panel color scheme without sourcing additional parts. The neoprene mounting gasket is included for a watertight panel installation. Non-corrosive plastic construction resists the harsh marine environment.

Parts Desk Insights
The RK19890TP is the right choice when you need a simple illuminated On/Off switch that is ignition-protection rated — the most common configuration for bilge blowers, fuel pump switches, and other single-circuit loads in or near the engine compartment where ignition protection is required by ABYC standards or good practice. The illuminated actuator makes it easy to confirm switch state at a glance in low-light conditions. For a non-illuminated ignition-protected switch with a more complex momentary DPDT circuit, the Sierra RK19850TP Contura III (On)-Off-(On) DPDT is the other Contura III option in this catalog. If ignition protection is not required for your application, the Sierra RK19000 Contura XIV On-Off SPST is a non-ignition-protected On/Off alternative, and the Sierra RK19070 Contura XIV On-Off DPST covers dual-pole switching without ignition protection.
