Sierra RK19440-1 Contura II Illuminated Rocker Switch, Off-On SPST, Weather Resistant

The Sierra RK19440-1 is an illuminated Contura II style rocker switch built for marine electrical panels where a compact, weather resistant off-on control is needed. It uses an off-on SPST circuit with a 1-way circuit type, so it simply opens or closes a single electrical path for the accessory it controls, such as a cabin light, bilge blower, or livewell pump. The switch panel mounts into a standard Contura II cutout and includes a neoprene mounting gasket to help seal the panel opening against moisture and spray, an important feature for helm stations and dashboards exposed to the marine environment.

Construction combines metal and plastic components with silver contact material for reliable current carrying, and the switch is rated for 20 amps. It carries an International Protection Rating of IP541 for resistance to dust and water intrusion. The compact 0.39 x 0.39 x 0.39 inch body fits into tight switch panel layouts alongside other Contura II series switches. This switch is designed for boats and other marine 12-volt style electrical systems where an illuminated, weather resistant rocker control is preferred over a standard toggle switch.
