The switch springs back to center-off the instant you release it in either direction — making it the correct choice for dual-direction momentary control applications such as trim tabs, windlasses, and actuators where you want the action to stop the instant you let go.\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 active position and returns cleanly to center-off when released. The rotary format gives a more precise, mechanical feel than a standard rocker switch, making it a preferred choice for premium helm panel builds where tactile quality matters. Sealed to IP67 for above-panel components. Fits industry-standard panel openings.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RS20030\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) — momentary both sides, springs to center-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\u003eTrim tab control requiring momentary dual-direction switching in a rotary format\u003c\/li\u003e\n\u003cli\u003eWindlass or anchor control requiring momentary deploy\/retrieve switching in a rotary format\u003c\/li\u003e\n\u003cli\u003eAny dual-direction momentary application where the tactile precision of a rotary control is preferred over a rocker switch\u003c\/li\u003e\n\u003cli\u003eMarine helm panels requiring IP67-rated momentary dual-direction 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 RS20030 is the right choice when you need dual-direction momentary control — trim tabs, windlasses, or similar applications — and prefer the precise, mechanical feel of a rotary switch over a standard rocker. The definitive detent gives clear tactile confirmation in each direction, and the momentary action ensures the function stops the instant you release the switch, which is the correct and safe behavior for these applications.
