| 29 | Latchable magnetic reed switch | US3775712D | 1973-03-12 | US3775712A | 1973-11-27 | LAUNT L |
| A U-shaped bar of so-called remanent magnetic material serves as a core for actuating one or more magnetic reed switches that are mounted between the legs of the U with their magnetic axes generally parallel with the bight of the U. Two coils are positioned around the bight of the U, one wound upon an axis parallel to the bight, and the other wound on an axis orthogonal to the bight. The switch, or switches are latched selectively and alternately in either their closed or open position, depending on which of the two coils is energized. The condition of the device may be sensed magnetically in a manner similar to the reading of magnetic memory devices.

| 988,383. Electrically released switches. WESTERN ELECTRIC CO. Inc. Feb. 22, 1962 [Feb. 27, 1961], No. 6880/62. Heading H2B. A switching device including a magnetic member which has a plurality of stable remanent magnetic states has one or more such members so shaped and located with respect to the contact members as to be magnetically influenced by a current pulse through the contacts, thereby setting the magnetic state of the member. As shown in Fig. 1, a sealed magnetic contact device has magnetically soft spring contact reeds 12, 13 biased apart in a glass tube 18 surrounded by interleaved windings A1-A2, B1, B2 within a cylindrical permalloy housing 11. The housing acts as a magnetic shield and a flux path between two annular ferrite remanent members 21, 22 around the contact terminals 14, 17. Additive energization of coils A1-A2, B1-B2 closes contacts 12, 13 and results in radial remanent magnetization of members 21, 22 (Fig. 3) which retains the contacts closed on de-energization of the coils. A high-amplitude, short duration current pulse though the contacts will change the magnetization pattern of members 21, 22 from radial to circular (Fig. 4) allowing the contacts 12, 13 to separate due to their inherent spring bias. As shown in Figs. 5 and 6, the remanent ferrite members 44, 47 may be mounted on the ends of contacts 27, 28 which are opened and closed on energization and de-energization of coils X1-X2, Y1-Y2. A current pulse in the contacts resulting in circular magnetization, retains the contacts closed. In Fig. 7 remanent members 58, 71 surround contacts 51, 52 and opening and closing of the contacts is dependant on the relative, most recent, energization of coils P1-P2, R1-R2, M1-M2, N1-N2. Opening by circular magnetization due to a current pulse through the contacts is effected as in Fig. 1. Specifications 522,798 and 870,906 are referred to. | ||||||

Disclosed is a magnetic latching relay having an asymmetrical solenoid structure, the magnetic latching relay comprising an electromagnet portion, a contacting portion, and a drive portion; the electromagnet portion comprises a magnetic conductive component, a coil rack, and a coil; the drive portion comprises a movable iron core; further comprising two pieces of permanent magnets, the two magnets being respectively disposed on the two sides of a coil axis and being respectively adjacent to or in contact with the corresponding sides of the magnetic conductive component; and the two pieces of permanent magnets are within the movement range of the movable iron core in the axial direction of the coil, and are biased towards the moving direction of the movable iron core when a contact is in the closed state, such that the retaining force of the moving iron core is substantially the same in both closed and open states of contact. The present invention introduces biased permanent magnets into a relay having a solenoid electromagnet portion structure to make the relay a magnetic latching relay, for ensuring low heat dissipation while solving the problem of unbalanced action reset voltage of a solenoid electromagnet portion, thus improving product performance and operational reliability. |
