Sierra MP78710 Marine Rotoswitch – Rotary On/Off Switch
The Sierra MP78710 Rotoswitch is a rotary-action On/Off switch designed for marine electrical panels. The knob-turn format provides a positive, tactile switching action that is easy to operate with wet hands or gloves — a practical advantage over rocker or push-pull switches in demanding on-the-water conditions. The rotary format also gives the helm panel a classic, purposeful look that suits both traditional and modern marine interiors.
The On/Off configuration makes it straightforward to use for any single-circuit switching application on a 12V DC marine electrical system — from bilge pumps and blowers to lighting and accessory circuits.

Parts Desk Insights
The MP78710 Rotoswitch is the right choice when you want a rotary-action switch for a single On/Off circuit — the knob-turn format is intuitive, easy to operate in rough conditions, and gives the panel a distinctive look compared to rocker or push-pull switches. If you prefer a push-pull format for the same On/Off function, the Sierra MP39530 Push-Pull Switch is the direct alternative. For a dual-circuit push-pull switch, the Sierra MP39580 Sequential Dual-Circuit Push-Pull Switch covers that application. For a sealed rocker switch format with IP66/68 protection, the Sierra Contura XIV Rocker Switch series offers a wide range of circuit configurations.
