| 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. | ||||||
| 94 | Method of establishing a relay contact arrangement | US367657 | 1995-01-03 | US5570072A | 1996-10-29 | George King |
| A method of establishing a contact arrangement for a reed switch. The method increases the number of contact surfaces between the armature and the fixed contact by providing the fixed contact with a contact end that has multiple prongs and positions the armature and the fixed contact so that the prongs surround the armature. The method also adjusts the armature and the fixed contact so that there are prongs that contact the armature when the armature moves from the rest position during switch operation and prongs that provide additional multi-planar contact surfaces for the armature in the event that the armature and the fixed contact prematurely separate during switch operation. | ||||||
| 95 | Reed spring relay construction | US904973 | 1978-05-11 | US4182999A | 1980-01-08 | Edward G. Walsh |
| An electrical reel spring relay construction in which the winding bobbin serves as the enclosing envelope. The bobbin has a longitudinal cavity therein, the cavity opening at each end of the bobbin in a tapered, wedge-shaped socket. Each spring member of the reed spring member pair has fitted thereabout near its terminal end a wedge-shaped sleeve dimensioned and formed to fit precisely in one of the cavity sockets. As so fitted, the spring members are positioned within the cavity so that their contact ends overlap. A contact gap spacing is determined by slightly oppositely angling the axes of the sockets from the longitudinal axis of the bobbin. | ||||||

| A movable magnetic armature of a size to nest within stepped faces on a fixed magnetic pole piece and on the armature support, respectively, is attached to the armature support by a conductive spring member which normally biases the armature away from the nested position in which it contacts a contact and stop member on the fixed pole. Imposition of the magnetic field causes the armature to move into closed contact position. The position of the armature even when in open contact position is close to the steps of the fixed pole piece as well as the armature support providing a low reluctance, short throw, quick action switch. | ||||||

| A sealed contact for use in electromagnetic relays has an inclined and/or indented contact cover together with an armature having a partial wedge-shaped cross section. The armature in its released state assumes a slanted position, and the electrical contacts are protected from voltage breakdown.

| 98 | Contact reed with foil-thin intermediate section | US40461273 | 1973-10-09 | US3866007A | 1975-02-11 | SHLESINGER JR BERNARD EDWARD; MARINER CHARLIE D |
| A reed for a reed switch which comprises a body of conductive material having a contact section, an intermediate spring section, and a support section with the intermediate section being foil-thin and a contact section being substantially rigid and non-flexible and thicker than the intermediate section, and the intermediate section comprises a leaf spring having a flexibility permitting one end of the leaf spring to flex a substantial distance through an arc with respect to the other end of the leaf spring without exceeding the elastic limits of the spring, and the intermediate section being cold-worked to a point where said conductive material assumes a substantial change in physical characteristics, and said intermediate section is substantially harder, less ductile, and more dense than the contact section, and the body of said reed being of magnetic material. The invention also includes a reed switch in which the reed is mounted in association with a second conductive nonmagnetic material reed and further is intended to include a magnetic operator for moving the magnetic reed into contact with the non-magnetic reed.

| A reed switch comprises a pair of reeds positioned so that the locus of operation of the free end of at least one of the reeds does not cross the other of the reeds. Contact material is provided in the area of the free end of each of the reeds. The contact material on at least one of the reeds is mounted to deviate from the free end of the one of the reeds.

| A mercury relay having nonsticking mercury wettable surfaces, one of the surfaces carrying a button of mercury wettable material surrounded by a rim of nonmercury wettable material, preferably tantalum, which extends beyond the button and forms a physical barrier against physical impact between the mercury wettable surfaces.
