A dry-reed switch with rhodium plated contacts for long life. When a magnet or electromagnet is brought near the reed magnetism is induced into both halves of the reed in the same direction. Thus of the overlapping ends one becomes a north pole & one a south pole & the attraction of the poles causes the switch to close. When the operating magnet is removed the springiness of the reed enables the switch to break.
