Abstract

An improved reed relay having a bobbin, an operating coil wound around the bobbin and at least one reed switch contained within the bobbin. The reed switch has a hermetically-sealed glass capsule that contains an atmosphere of dry inert gas. The capsule also contains two long thin contact blades having terminations extending from respective ends of the capsule. A first contact blade acting as the armature is formed at its contact end with multiple prongs, each prong containing a contact pad. The second contact blade acts as the fixed contact. The contact pads surround the contact end of the second blade so as to contact, during operation of the relay, a different surface area of the second blade. The prongs may be formed in any desired geometric arrangement (e.g., rectangular, triangular, etc.) to surround the contact end of the second contact blade.
