Sierra RS20010 Contura Marine Rotary Switch – Off-(On), Momentary, IP67, Definitive Detent
The Sierra RS20010 is a Contura marine rotary switch with an Off-(On) momentary configuration. The switch springs back to off the instant you release it — there is no maintained on position. This makes it the correct choice for any application where you want momentary contact behavior with the tactile precision and definitive detent feel of a rotary control rather than a standard push-button or rocker switch.
The patented mechanism translates rotary motion into linear switching action, and a secondary cam provides definitive detent positions — the switch clicks firmly into the active position and returns cleanly to off when released. Sealed to IP67 for above-panel components. Fits industry-standard panel openings for straightforward installation in new builds and retrofits.

Parts Desk Insights
The RS20010 is a specialized switch — choose it when you specifically want momentary contact behavior in a rotary format. The definitive detent gives a more precise, mechanical feel than a standard push-button, which can be a preference for premium helm panel builds where tactile quality matters. If you need a maintained two-position rotary switch with a red/green LED indicator rather than a momentary switch, the Sierra RS20000 Contura On-On Rotary Switch is the maintained two-position alternative in the same series. For a compact momentary rocker switch in a standard rectangular cutout, the Sierra RK40830 Compact Off-(On) SPST covers momentary applications in a rocker format.
