Sierra RS20060 Contura Marine Rotary Switch – Off-On-On, 3-Position (Off/1/1&2 Maintained), IP67, Definitive Detent

Sierra RS20060 Contura Marine Rotary Switch – Off-On-On, 3-Position (Off/1/1&2 Maintained), IP67, Definitive Detent

The Sierra RS20060 is a Contura marine rotary switch with a three-position Off-On-On configuration labeled Off / 1 / 1&2. All active positions are maintained — the switch stays in whichever position you select until you move it again. Position Off disconnects all banks, Position 1 connects Battery Bank 1 only, and Position 1&2 connects both banks simultaneously and holds that connection continuously.

The key distinction from the RS20050 is that the 1&2 position on the RS20060 is maintained rather than momentary — both banks stay connected for as long as the switch remains in that position. This makes the RS20060 the correct choice for installations where continuous parallel operation of both banks is intentional, such as charging both banks simultaneously from a single alternator or shore power source. The patented mechanism translates rotary motion into linear switching action, and a secondary cam provides definitive detent positions. Sealed to IP67 for above-panel components. Fits industry-standard panel openings.

Key Specifications

• Part Number: 11-RS20060
• Series: Contura
• Switch Type: Rotary (patented rotary-to-linear mechanism)
• Configuration: Off-On-On, 3-position — Off / Bank 1 (maintained) / Banks 1&2 (maintained)
• Position Off: All banks disconnected
• Position 1: Battery Bank 1 only — maintained
• Position 1&2: Both banks simultaneously — maintained, stays connected until switched
• Illumination: None

• Note: (On) in parentheses designates a momentary position; no parentheses indicates a maintained position

Compatible Applications

• Marine battery management where continuous parallel operation of both banks is required (e.g., charging both banks from a single source)
• Installations where both banks need to remain connected simultaneously for extended periods
• Marine helm panels requiring IP67-rated three-position battery management rotary switches with all maintained positions
• New helm panel builds and retrofits using industry-standard panel openings

Parts Desk Insights

The RS20060 is the right choice when you need the 1&2 position to stay connected continuously — the maintained 1&2 position is suited to charging scenarios where you want both banks to receive charge simultaneously without having to hold the switch. The critical difference from the Sierra RS20050 is that the RS20050’s 1&2 position is momentary (springs back when released), while the RS20060’s 1&2 position is maintained (stays connected). Choose the RS20050 if you want to prevent accidental continuous parallel connection; choose the RS20060 if continuous parallel operation is intentional and expected. For a fully maintained three-position 1-2-Both selector with no off position, the Sierra RS20040 On-On-On 1-2-3 Battery Selector is the no-off alternative.
