Sierra RK40630B Marine Rocker Switch – On-On, SPST, No Off Position, Blue Halo LED, IP68, 20A
The Sierra RK40630B is a premium marine rocker switch with an On-On SPST (Single Pole, Single Throw) configuration and a blue Halo LED illumination system. Unlike most rocker switches, the RK40630B has no off position — it is always in one of two maintained on states. This makes it the correct choice for source selection and mode switching applications where the circuit must remain active continuously and you simply need to choose which of two states it is in, while maintaining the premium Halo LED look across the panel.
The 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 indicates the active state. 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 Sierra RS20200 Terminal Housing and either the Sierra RS20180 (17-20 AWG) or Sierra RS20190 (13.5-17 AWG) crimp terminals are required for wiring.

Parts Desk Insights
The RK40630B is a specialized switch — choose it specifically when your application requires the circuit to always be in one of two active states with no off position, and you want to maintain Halo LED visual consistency across the panel. Verify your wiring diagram before ordering to confirm you need On-On rather than On-Off. For the standard maintained On-Off version of the same Halo SPST switch in blue, the Sierra RK40610B Blue Halo On-Off SPST is the latching On-Off alternative. For the momentary (On)-Off version in blue, the Sierra RK40620B Blue Halo (On)-Off Momentary covers momentary applications. Note that wiring this switch requires the Sierra RS20200 Terminal Housing and the appropriate crimp terminals — standard spade terminals will not fit the dedicated TE connector.
