Sierra RS20000 Contura Marine Rotary Switch – On-On, Red/Green LED, IP67, Definitive Detent
The Sierra RS20000 is a premium Contura marine rotary switch with an On-On configuration and a dual-color red/green LED indicator. The switch illuminates red in one position and green in the other, providing immediate, unambiguous visual confirmation of which mode or circuit state is active — making it the ideal choice for bilge pump auto/manual selectors, battery mode switches, and any application where you need to know at a glance which of two active states the switch is in.
Unlike a standard rocker switch, the RS20000 uses a patented mechanism that translates rotary motion into linear switching action, combining the tactile precision of a rotary control with the panel footprint of a standard switch opening. A secondary cam provides definitive detent positions — the switch clicks firmly into each position 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 RS20000 is the right choice when you need more than just a switch — the red/green dual-color LED makes the active state immediately visible from across the helm, and the definitive detent mechanism eliminates any doubt about which position the switch is in. This combination makes it purpose-built for bilge pump auto/manual selectors and battery mode switches where an ambiguous switch position is a real operational risk. The On-On configuration means there is no off position — the switch is always routing to one of two states, which is the correct behavior for these applications. For a simpler On/Off rotary switch without LED indication, the Sierra MP78710 Marine Rotoswitch is an alternative rotary On/Off option. 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.
