Sign up for Blue Sea Systems Contura III SPDT Switch | (ON)-OFF-ON Toggle For Marine, RV & Off-Grid Use
If you’re wiring up a boat, RV, camper, or any off-grid setup, you know you need switches that can handle rough conditions.
This Blue Sea Systems Contura III switch is built tough.
It’s a SPDT (ON)-OFF-ON toggle, meaning you can control two circuits or have a center-off position.
Rated for 20A at 12V DC, it’s perfect for lighting, fans, pumps, or accessories.
The housing is designed to resist vibration, shock, moisture, and salt spray — so it won’t quit on you when it counts.
It fits right into Blue Sea’s Contura waterproof panels, but works in any standard cutout.
The black finish looks clean and professional.
Installation is straightforward: just wire it up, snap it into place, and you’re set.
Reliable, durable, and from a brand that boaters and builders trust.
No flickering, no failure — just solid performance.
