A Reliable On/Off Rocker That Snaps Right Into Standard Marine Panels
The Sea-Dog Large SPST On/Off Rocker Switch is a straightforward, dependable maintained rocker for marine accessory circuits. Snap it into any standard 7/8" × 1-7/16" panel slot — no tools, no hardware, no drilling — and wire it up with standard 1/4" blade terminals. It’s the kind of switch that belongs on every boat: simple to install, easy to replace, and built to handle everyday switching loads reliably.
Constructed from durable injection-molded nylon and stamped brass, this switch handles 15A at 12V DC — sufficient for most single-circuit marine accessories including lighting, blowers, and small pumps.

Parts Desk Insights
Best use case: This is the right switch when you need a reliable, no-frills On/Off rocker that drops into a standard panel slot without any fuss — ideal for replacing a worn or broken rocker in an existing panel, or for populating open switch positions in a multi-gang panel build. The snap-in design means the swap takes minutes, and the 1/4" blade terminals are compatible with the pre-terminated leads found on most marine panel wiring harnesses. At this price point it’s practical to stock a few spares aboard.
