Standex International Corp/de/
A diversified industrial manufacturer based in Salem, New Hampshire, Standex makes specialized components used in electronics, aerospace, medical devices, and scientific research — including reed switches and sensors, magnetic power components, and engraving services for mold texturizing. It was founded in 1955 by John Bolten, Sr., who reinvested the proceeds from selling his vinyl company into a religious publisher and a steel engraving firm, incorporating them as Standard International before adopting the Standex name in 1973. Its electronics arm is the world's largest maker of reed switches, tiny magnetically operated switches that use no power when open.
