Reed Switches | Introduction

Reed Switches reliably switch billions of operations. A reed switch uses simple magnet interaction to open and close it's contacts. And they consume no power in their 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 reed switch series is one of the world's smallest (3.95mm). Also the molded MK24 series surface mount design. These small switches have unique switching capabilities. So new applications in home appliances and low power devices are leading the reed switch industry. 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.

Bi-stable / Latching Reed Switch

A latching reed switch is an ideal solution in extremely low power requirements, particularly in battery powered devices. It is also referred to a or bi-stable (1 Form E) reed switch. Latching reed switches use two permanent magnets to achieve the latching function. The first magnet is partially magnetized. Bringing the contacts closer together, but they still remain open. The second magnet with an aiding field brought close to the switch will close the contacts.  And they will remain closed until the second magnet is brought close but this time with a reversed magnetic field. So a latching reed switch can exist in either the normally open (N.O.) or normally closed (N.C.) contact state. And the contact state is controlled by reversing the magnetic field of the second magnet.

Changeover Reed Switch

A changeover reed switch has three contact leads. Form C or double throw switch described the switching function as break-before-make. The switching sequence is as follows. One contact opens its connection to another contact and then closes its connection to a third contact. Furthermore contact configuration is the number of switches or poles used in a component. So a single pole double throw (SPDT) device contains a single changeover switch. Likewise double pole double throw (DPDT) contains to 2 changeover switches in a component. Finally changeover reed switches can also be used in a normally closed or Form B contact configuration. Standex offers a 100 watt high power KSK-1C10 switch for changeover applications. And for even greater versatility the ORT551 series form C changeover switch meets most application requirements. We package the ORT551 series in one of two ways. One is a miniature 14mm bare glass surface mount version MK23-90. And the second version is the environmentally sealed SMD MK01 series. Furthermore both series come in tape and reel packaging per IEC 286/part 3 standards. So manufacturing is easy with pick and place automation. Standex Electronics also integrates the ORT551 into various standard sensor and reed relay series. Don't see what you're looking for? We specialize in value-add and custom assembly.
