Both active positions are momentary — the switch springs back to center-off as soon as you release it — while routing a single circuit to either of two outputs. This makes it the standard choice for dual-direction momentary control: trim tabs, windlasses, actuators, and any application where you want the action to stop the instant you let go of the switch.\u003c\/p\u003e\u003cp\u003eThe high-profile rocker action delivers a crisp, positive feel with every press, giving clear tactile confirmation in each direction. Its compact body fits a standard rectangular panel cutout. Rated for both AC and DC operation — 12A at 125V AC, 10A at 250V AC, and suitable for 12V and 24V DC systems.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RK40870\u003c\/li\u003e\n\u003cli\u003eSwitch Type: Compact Rocker, (On)-Off-(On)\u003c\/li\u003e\n\u003cli\u003eCircuit Configuration: SPDT (Single Pole, Double Throw)\u003c\/li\u003e\n\u003cli\u003eAction: Momentary both sides — springs to center-off when released\u003c\/li\u003e\n\u003cli\u003eAC Rating: 12A at 125V AC \/ 10A at 250V AC\u003c\/li\u003e\n\u003cli\u003eDC Rating: Suitable for 12V and 24V DC systems\u003c\/li\u003e\n\u003cli\u003ePanel Cutout: Standard rectangular\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 single-pole up\/down switching\u003c\/li\u003e\n\u003cli\u003eWindlass or anchor control requiring momentary deploy\/retrieve switching\u003c\/li\u003e\n\u003cli\u003eAny dual-direction, single-circuit momentary function on a marine helm panel\u003c\/li\u003e\n\u003cli\u003eMarine DC panels for 12V and 24V dual-direction momentary switching\u003c\/li\u003e\n\u003cli\u003eAC circuit dual-direction momentary switching\u003c\/li\u003e\n\u003cli\u003eAny panel using a standard rectangular rocker switch cutout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe RK40870 is the compact series choice for dual-direction momentary control — the circuit is only active while you’re pressing it in either direction, which is the correct and safe behavior for trim tabs and windlasses where you want the function to stop the instant you release the switch. The compact body makes it a practical fit for secondary panels, smaller helm layouts, or any installation where the full-size Contura XIV footprint is too large. For a non-illuminated, non-ignition-protected Contura XIV version of the same (On)-Off-(On) SPDT momentary circuit in a larger switch body, the \u003ca href=\"\/products\/sierra-rk19060-contura-xiv-marine-rocker-switch-on-off-on-spdt-momentary-both-sides\"\u003eSierra RK19060 Contura XIV (On)-Off-(On) SPDT\u003c\/a\u003e is the full-size alternative.
