Sierra RS20020 Contura Marine Rotary Switch – On-Off-On, Red LED, IP67, Definitive Detent
The Sierra RS20020 is a Contura marine rotary switch with a maintained On-Off-On configuration and a red LED indicator. 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.
The 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.

Parts Desk Insights
The 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 Sierra RS20000 Contura On-On Rotary Switch is the two-position alternative. For a momentary rotary switch that springs back to off when released, the Sierra RS20010 Contura Off-(On) Momentary Rotary Switch covers that application. For a rocker-style On-Off-On SPDT switch with a red LED indicator, the Sierra RK19320 Contura V On-Off-On SPDT covers that application in a rocker format.
