SPDT Changeover (Form C) Reed Switch |

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. Check out our Magnet Interaction page to see animated examples of how reed switches are used in a sensing environment.
