The B126J switch series from Electroswitch Corporation offers single-pole double-throw (SPDT) rocker switches designed for applications requiring reliable switching between two positions. These switches come in various voltage ratings, making them suitable for a wide range of electronic projects and systems.

If you're working on anything that needs a simple toggle between two states—like a power switch, a mode selector, or a control input for a device—the B126J series is a solid choice. They’re robust and offer good tactile feedback, which is crucial for user interfaces that require clear on/off or select/deselect actions.

One thing worth noting is the variety of voltage ratings available.
