Three-Position Maintained DPDT Rocker for Dual-Circuit and Reversing Applications
The Sea-Dog Large DPDT On/Off/On Rocker Switch gives you three maintained positions — On, Off, and On — in the same snap-in large rocker format that fits standard 7/8" × 1-7/16" marine panel cutouts. Double Pole, Double Throw (DPDT) configuration means this switch controls two separate circuits simultaneously, making it the right choice for reversing motor circuits, dual-output accessories, and any application where you need to switch two circuits in tandem from a single rocker.
Unlike a momentary switch, both outer On positions are maintained — the switch stays in position until you move it, so the connected circuit stays active without holding the rocker. Built from durable injection-molded nylon and stamped brass, it snaps into place and wires up with standard 1/4" blade terminals.

Parts Desk Insights
Best use case: The DPDT On/Off/On maintained rocker is the right switch when you need to reverse a motor circuit and want the motor to keep running without holding the switch — ideal for trim tab systems, actuator controls, and wiper motors where a maintained position is preferred over momentary. The DPDT configuration handles both poles of the motor circuit simultaneously, eliminating the need for a separate relay in most low-current reversing applications. If your application requires the motor to stop as soon as you release the switch, use the momentary version instead.

For a simple SPST On/Off large rocker in the same panel format, the Sea-Dog Large SPST On/Off Rocker Switch is the straightforward option. For a complete panel solution, the Sea-Dog Splash Gard 6-Gang Rocker Switch Panel pairs well for full helm builds.
