Standex Electronics offers the most comprehensive listing of magnetic reed switches that cover the majority of low power switching requirements. Reed switches have unique switching capabilities making them an ideal choice in more and more new applications. For example, Standex Electronics offers a magnetic reed switch where the overall glass length is only 3.95 mm long (KSK-1A04) - the smallest in the industry. These small sizes pave the way for unique new applications in RF switching, medical applications and many more. Also driving these new switching applications is the ever broadening of new reed relay, reed sensor and fluid level designs by Standex Electronics. Hermetically sealed reed switches (glass to metal seal) are impervious to almost all environments. This opens up a vast number of applications where they are the only technology capable of meeting specific requirements where certain mechanical switches and semiconductor switches are environmentally limited. Many thousands of reed switch applications currently exist with many more added on a regular basis. Reed relays and reed sensors both use the reed switch as the heart of their switching mechanism. These applications span across all the major market segments. Standex Electronics’ extensive business partnership has made us the preferred worldwide source for KOFU Reed Switches (formerly OKI) such as ORD211, ORD213, ORD219, ORD228VL, ORD311, ORD312, ORD314, ORD324, ORD872, ORD2210, ORD2210V, ORD2211, ORT551, and ORT551-1. Our engineers are always available to discuss your design requirements where specialized packaging is available in a very economical manner.

Changeover Reed Switch products are a changeover or single-pole double throw SPDT reed switch type where a normally closed contact opens before a normally open contact closes. A changeover reed switch is also referred to as a (Form C) reed switch or break-before-make (Form C) which defines the sequence in which one contact opens its connection to another contact and then closes its connection to a third contact. Changeover reed switches can also be used as a (Form B), normally closed reed switch (N.C.) in a reed relay or reed sensor application.
