The switch has three positions — two active on states with a center-off between them — and illuminates red when in an active on position, providing clear visual confirmation that the circuit is energized. The center-off position gives a definitive off state between the two active positions.\u003c\/p\u003e\u003cp\u003eThe patented mechanism translates rotary motion into linear switching action, and a secondary cam provides definitive detent positions — the switch clicks firmly into each of the three positions with no ambiguity about which state it’s in. Sealed to IP67 for above-panel components. Fits industry-standard panel openings for straightforward installation in new builds and retrofits.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RS20020\u003c\/li\u003e\n\u003cli\u003eSeries: Contura\u003c\/li\u003e\n\u003cli\u003eSwitch Type: Rotary (patented rotary-to-linear mechanism)\u003c\/li\u003e\n\u003cli\u003eConfiguration: On-Off-On (maintained) — two active positions with center-off\u003c\/li\u003e\n\u003cli\u003eLED Indicator: Red — illuminates in on position(s)\u003c\/li\u003e\n\u003cli\u003eDetent: Secondary cam with definitive click positions\u003c\/li\u003e\n\u003cli\u003eSealing: IP67 (above-panel components)\u003c\/li\u003e\n\u003cli\u003ePanel Opening: Industry-standard fit\u003c\/li\u003e\n\u003cli\u003eNote: (On) in parentheses designates a momentary position\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSource selection or mode switching requiring a center-off position with red on-indicator confirmation\u003c\/li\u003e\n\u003cli\u003eMarine helm panels where a three-position rotary switch with red LED status indication is preferred over a rocker\u003c\/li\u003e\n\u003cli\u003eApplications requiring the tactile precision and definitive detent of a rotary control with On-Off-On switching\u003c\/li\u003e\n\u003cli\u003eMarine helm panels requiring IP67-rated three-position rotary switches\u003c\/li\u003e\n\u003cli\u003eNew helm panel builds and retrofits using industry-standard panel openings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe RS20020 is the right choice when you need a three-position On-Off-On rotary switch with a red on-indicator and a definitive center-off — the rotary format gives a more precise, mechanical feel than a rocker switch, and the definitive detent eliminates any doubt about which position the switch is in. The red LED confirms when an active position is engaged. If you need a two-position On-On rotary switch with a dual red\/green LED indicator (no center-off), the \u003ca href=\"\/products\/sierra-rs20000-contura-marine-rotary-switch-on-on-red-green-led-ip67-definitive-detent\"\u003eSierra RS20000 Contura On-On Rotary Switch\u003c\/a\u003e is the two-position alternative.
