Sierra Push-Pull Switches
Sierra Push-Pull Switches: Built for the Marine Environment
When reliability on the water is non-negotiable, the quality of every switch on your control panel matters. Sierra has long been a trusted name in marine electrical components, and their line of push-pull switches reflects that commitment to durability, precision, and ease of installation. Whether you're upgrading an aging helm panel or replacing a failed switch mid-season, Sierra's push-pull offerings deliver the dependable performance boaters demand.
Solid Construction Engineered for Harsh Conditions
What sets Sierra's push-pull switches apart from generic alternatives starts with the materials. Solid brass construction paired with stainless steel springs gives these switches the structural integrity and corrosion resistance required for a saltwater or freshwater marine environment. The result is a switch that cycles cleanly, resists the oxidation that plagues lesser hardware, and holds up to the vibration and moisture exposure inherent in on-water use.
Sierra's heavy-duty push-pull switches are rated at 15 amps at 12V DC and 25 amps at 24V DC, making them well-suited for a wide range of onboard electrical circuits. A 3/8-inch diameter mounting stem fits control panels up to 1 inch thick, while screw terminals provide secure, tool-friendly wiring connections that don't require wire lugs.
Multiple Configurations for Versatile Panel Builds
Sierra offers push-pull switches in several circuit configurations to match virtually any marine panel layout:
- SPST Off/On (MP39520): A straightforward single-circuit switch — pull for on, push for off. Ideal for lights, blowers, or bilge pumps.
- SPDT and multi-position models: Options like the MP39570 and MP39580 allow the first pull to energize circuit 1, with a second pull energizing both circuits 1 and 2 simultaneously.
- Dual-circuit models (MP39600): Designed to energize two separate circuits in a single ON position, simplifying panel wiring for accessories that must operate together.
- 3-Position heavy-duty switches: Off–On(1)–On(1&2) configurations in an SPDT layout give installers precise control over staged circuit activation from a single panel cutout.
A Warranty That Backs Every Switch
Sierra is operated under Dometic Marine and carries one of the most confident warranties in the industry. Sierra products are warranted to be free of defects in workmanship and materials for the useful life of the product — a rare lifetime-of-product coverage that speaks directly to how these switches are built. Should any Sierra product fall short, it will be repaired or replaced at no charge.
Drop-In Replacements Across Major Brands
Because Sierra designs its push-pull switches to meet or exceed OEM standards, many models serve as direct cross-replacements for parts from Attwood, Sea Sense, Seadog, and Valeo. This makes Sierra an especially practical choice when sourcing a replacement switch by function rather than by original brand — you get equivalent or better performance without hunting down an obsolete part number.
