It lets you route a single circuit to one of two outputs — or cut power entirely in the center position. Whether you're switching between two bilge pump speeds, toggling between two lighting zones, or controlling a reversible actuator, this switch gives you clean, reliable control in a compact contura-style footprint.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Contura2 (contura-style rocker)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Configuration:\u003c\/strong\u003e SPDT — Single Pole, Double Throw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e On\/Off\/On — latching (stays in position)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e BSS-7931\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 60 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBest Use Cases\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSwitching between two lighting zones or circuits\u003c\/li\u003e\n\u003cli\u003eTwo-speed bilge pump or blower control\u003c\/li\u003e\n\u003cli\u003eReversible actuator or trim tab direction control\u003c\/li\u003e\n\u003cli\u003eAny application requiring a single-pole, three-position latching switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible Contura2 Switches\u003c\/h3\u003e\n\u003cp\u003eBuilding out a switch panel?
