Reed Switches | Introduction

Reed Switches reliably switch billion of operations. A reed switch uses simple magnet interaction to open and close while consuming no power in its normally open state. Reed switches are hermetically sealed so they can exist or be used in almost any environment. This is not the case for electromechanical and semiconductor switches. Our KSK-1A04 switch series is one of the smallest (3.95mm) in the industry along with our MK24 series surface mount design. These small sizes and unique switching capabilities are paving the way for many new applications in home appliances and low power devices. Standex Electronics is the world’s largest reed switch manufacturer. We produce more than 700 million reed contacts per year. Our switches feature the highest range of sizes, unique switching capabilities, quality and life expectancy. Since acquiring OKI reed switch manufacturing, Standex Electronics is the preferred worldwide source for reed switch technology. Some of our highest demanded switches are the ORD211, ORD213, ORD324, and ORT551, series. We are experts in specialized sensor packaging.  Contact our engineers to discuss your design requirements.
