Sierra RK21880 Marine Snap-In Rocker Switch – Replacement for RK22070 Panel, 20A/12VDC
The Sierra RK21880 is a direct replacement rocker switch designed to snap into the Sierra RK22070 marine switch panel. When an individual switch in your RK22070 panel wears out or fails, the RK21880 lets you replace just that switch rather than the entire panel — a straightforward repair that restores full panel function without rewiring. The switch snaps securely into the panel’s 7/16" x 1-1/4" rectangular cutout and connects via 1/4" male blade terminals.
Solid black plastic construction matches the panel’s original appearance. Rated at 20A at 12V DC, it handles the same load capacity as the original switches in the panel.

Parts Desk Insights
The RK21880 is the right choice when you have a Sierra RK22070 switch panel and need to replace one or more individual switches without swapping out the entire panel. This is the most cost-effective repair path for a panel where only one or two switches have failed — the snap-fit design makes replacement straightforward without special tools. Verify the 7/16" x 1-1/4" rectangular cutout dimension against your panel before ordering if you’re unsure whether your panel is the RK22070. If you need a full-featured standalone rocker switch for a new panel build rather than a panel replacement, the Sierra Contura XIV rocker switch series offers IP66/68-sealed options across a wide range of circuit configurations.
