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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RK19040\u003c\/li\u003e\n\u003cli\u003eSeries: Contura XIV\u003c\/li\u003e\n\u003cli\u003eSwitch Type: Rocker, On-Off-On (maintained both sides)\u003c\/li\u003e\n\u003cli\u003eCircuit Configuration: SPDT (Single Pole, Double Throw)\u003c\/li\u003e\n\u003cli\u003eAction: Maintained both sides with center-off — routes single circuit to either of two outputs\u003c\/li\u003e\n\u003cli\u003eContact Mechanism: Silver-plated butt contact\u003c\/li\u003e\n\u003cli\u003eConstruction: Greaseless — rated for extreme temperatures\u003c\/li\u003e\n\u003cli\u003eSealing: IP66\/IP68\u003c\/li\u003e\n\u003cli\u003ePanel Seal: Included — prevents water ingress beneath panel\u003c\/li\u003e\n\u003cli\u003eActuator: Removable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSource selection between two circuits with a center-off position on a Contura XIV panel\u003c\/li\u003e\n\u003cli\u003eMode switching applications requiring two maintained active states and a clear off position\u003c\/li\u003e\n\u003cli\u003eMarine helm panels requiring On-Off-On SPDT switching with silver butt contact construction\u003c\/li\u003e\n\u003cli\u003eInstallations in extreme temperature environments where greaseless contact construction is required\u003c\/li\u003e\n\u003cli\u003eReplacement for worn or damaged On-Off-On SPDT Contura XIV rocker switches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe 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.
