Sierra RK19040 Contura XIV Marine Rocker Switch – On-Off-On, SPDT, IP68, Silver Butt Contact, Greaseless
The Sierra RK19040 is a marine rocker switch from the Contura XIV series with a maintained On-Off-On SPDT (Single Pole, Double Throw) configuration. The SPDT circuit routes a single input to either of two outputs, with a center-off position between the two active states. Both active positions are maintained — the switch stays in whichever position you select until you move it again. This makes it the standard choice for source selection and mode switching applications where you need to choose between two circuit paths with a clear off state between them.
The Contura XIV uses a silver-plated butt contact mechanism rather than blade terminals, providing maximum contact reliability and consistent performance across a wide temperature range. The greaseless construction is specifically designed for extreme temperature environments. Sealed to IP66/68. A panel seal prevents water ingress beneath the panel surface. The removable actuator allows style changes or replacement without removing the switch body from the panel.

Parts Desk Insights
The RK19040 is the right choice when you need On-Off-On SPDT source selection or mode switching with the Contura XIV’s silver butt contact and greaseless construction — the center-off gives a definitive off state between the two active positions, which is the correct configuration for most source selection applications where you want to confirm the circuit is off before switching between sources. The silver butt contact and greaseless design give it a reliability and temperature range advantage over blade-terminal switches in demanding environments. For the same On-Off-On SPDT circuit in the Contura XIV series, the Sierra RK19050 Contura XIV On-Off-On SPDT is a variant in the same series — verify the actuator style difference before ordering. For a simple On/Off SPST in the same series, the Sierra RK19000 Contura XIV On/Off SPST covers single-circuit on/off applications. For a dual-pole On-Off-On DPDT in the same series, the Sierra RK19090 Contura XIV On-Off-On DPDT covers dual-circuit source selection.
