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 single-circuit momentary application where you want the premium Halo LED look: horn activation, alarm tests, bilge pump manual overrides, and similar momentary-contact functions.\u003c\/p\u003e\u003cp\u003eThe Halo LED provides two independent illumination zones: a perimeter ring around the actuator that glows continuously as a backlight, and a separate actuator illumination that activates when the switch is pressed. Sealed to IP68 for full submersion protection. Rated at 20A at 12V DC. Fits industry-standard panel cutouts. Uses a dedicated TE connector with .110 terminals — the \u003ca href=\"\/products\/sierra-rs20200-terminal-housing-for-halo-rocker-switches-direct-fit-connector-body\"\u003eSierra RS20200 Terminal Housing\u003c\/a\u003e and either the \u003ca href=\"\/products\/sierra-rs20180-tin-crimp-terminals-for-halo-rocker-switches-17-20-awg-15a-10-pack\"\u003eSierra RS20180 (17-20 AWG)\u003c\/a\u003e or \u003ca href=\"\/products\/sierra-rs20190-tin-crimp-terminals-for-halo-rocker-switches-13-5-17-awg-15a-10-pack\"\u003eSierra RS20190 (13.5-17 AWG)\u003c\/a\u003e crimp terminals are required for wiring.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RK40620B\u003c\/li\u003e\n\u003cli\u003eSwitch Type: Rocker, (On)-Off\u003c\/li\u003e\n\u003cli\u003eCircuit Configuration: SPST (Single Pole, Single Throw)\u003c\/li\u003e\n\u003cli\u003eAction: Momentary — springs to off when released\u003c\/li\u003e\n\u003cli\u003eLED Color: Blue\u003c\/li\u003e\n\u003cli\u003eIllumination: Dual-zone Halo — perimeter ring backlight + actuator illumination when pressed\u003c\/li\u003e\n\u003cli\u003eSealing: IP68\u003c\/li\u003e\n\u003cli\u003eCurrent Rating: 20A at 12V DC\u003c\/li\u003e\n\u003cli\u003ePanel Cutout: Industry-standard fit\u003c\/li\u003e\n\u003cli\u003eWiring: Dedicated TE connector, .110 terminals (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHorn activation requiring a momentary contact switch with premium Halo LED styling\u003c\/li\u003e\n\u003cli\u003eAlarm test, bilge pump manual override, or other momentary-contact functions on a Halo LED panel\u003c\/li\u003e\n\u003cli\u003eMarine helm panels where Halo LED consistency across all switches is desired, including momentary functions\u003c\/li\u003e\n\u003cli\u003e20A at 12V DC momentary marine accessory circuits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe RK40620B is the right choice when you need a momentary switch on a Halo LED panel — the circuit is only active while you’re pressing it, which is the correct behavior for horns, alarms, and manual override functions, and the Halo LED styling keeps the panel visually consistent with the maintained Halo switches around it.
