Sierra RK40650B Marine Rocker Switch – On-Off, DPST, Blue Halo LED, IP68, 20A
The Sierra RK40650B is a premium marine rocker switch with a maintained On-Off DPST (Dual Pole, Single Throw) configuration and a blue Halo LED illumination system. The DPST circuit simultaneously switches two independent circuits with a single rocker action — both circuits turn on together and turn off together. This makes it the correct choice for applications where two circuits must always be switched in unison, such as dual-feed power circuits, paired accessory loads, or any application where independent switching of the two circuits is not required.
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 switch state. Sealed to IP68 for full submersion protection. Rated at 20A at 12V DC per pole. 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 RK40650B is the right choice when you need to switch two circuits simultaneously with a single switch and want the premium Halo LED look — the DPST configuration is the correct fit for dual-feed circuits and paired loads where independent switching of the two poles is not needed. If you need to switch two circuits independently or route them to different outputs, a DPDT switch is the correct choice instead. For the single-circuit On-Off SPST version of the same Halo switch in blue, the Sierra RK40610B Blue Halo On-Off SPST is the single-pole alternative. For a dual-circuit On-Off-On DPDT Halo switch in blue, the Sierra RK40700B Halo DPDT On-Off-On covers dual-pole source selection 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.
