The SPDT configuration routes a single circuit to either of two outputs, with a center-off position in between — making it the standard choice for source selection, mode switching, and any application where you need to choose between two circuit paths with a clear off state.\u003c\/p\u003e\u003cp\u003eIts compact body fits a standard rectangular panel cutout. Rated for both AC and DC operation — 12A at 125V AC, 10A at 250V AC, and suitable for 12V and 24V DC systems — making it a versatile option for mixed AC\/DC panel builds.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 11-RK40850\u003c\/li\u003e\n\u003cli\u003eSwitch Type: Compact Rocker, On-Off-On (maintained)\u003c\/li\u003e\n\u003cli\u003eCircuit Configuration: SPDT (Single Pole, Double Throw)\u003c\/li\u003e\n\u003cli\u003eAction: Maintained both sides — stays in position when released; center-off between active positions\u003c\/li\u003e\n\u003cli\u003eAC Rating: 12A at 125V AC \/ 10A at 250V AC\u003c\/li\u003e\n\u003cli\u003eDC Rating: Suitable for 12V and 24V DC systems\u003c\/li\u003e\n\u003cli\u003ePanel Cutout: Standard rectangular\u003c\/li\u003e\n\u003cli\u003eNote: (On) in parentheses on any switch in this series designates a momentary position\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\u003c\/li\u003e\n\u003cli\u003eMode switching applications requiring two maintained active states and a clear off position\u003c\/li\u003e\n\u003cli\u003eMarine DC panels for 12V and 24V three-position switching\u003c\/li\u003e\n\u003cli\u003eAC circuit source selection on shore power panels\u003c\/li\u003e\n\u003cli\u003eAny panel using a standard rectangular rocker switch cutout requiring a maintained On-Off-On SPDT switch\u003c\/li\u003e\n\u003cli\u003eReplacement for worn or damaged compact On-Off-On SPDT rocker switches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe RK40850 is the standard compact SPDT switch for source selection and mode switching — the center-off position gives you a clear off state between the two active positions, which is the correct configuration for most switching applications where you want to confirm the circuit is off before changing direction or source. If you need both active positions to be momentary (springs back to center-off when released), the \u003ca href=\"\/products\/sierra-rk40870-compact-rocker-switch-on-off-on-spdt\"\u003eSierra RK40870 Compact (On)-Off-(On) SPDT\u003c\/a\u003e is the momentary alternative in the same compact series.
