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.\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 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.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RS20010\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: Off-(On) momentary — springs to off when released\u003c\/li\u003e\n\u003cli\u003eIllumination: None\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\u003eMomentary contact applications requiring the tactile precision and definitive detent of a rotary control\u003c\/li\u003e\n\u003cli\u003eHorn activation, alarm test, or other momentary-contact functions where a rotary format is preferred over a push-button or rocker\u003c\/li\u003e\n\u003cli\u003eMarine helm panels requiring IP67-rated momentary 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 RS20010 is a specialized switch — choose it when you specifically want momentary contact behavior in a rotary format.
