摘要： An electric switching unit for preventing oxidation of copper-base contacts in contactors comprises a body (2), comprises an electromagnet (11) having a stationary yoke (7) and a moving armature (15) in cooperating relation with a plurality of switches (36). A protective casing (42) is fixed on the body so as to contain the switches. The contact-studs (30, 31, 32, 33) of the switches (36) essentially have a base of cuprous materials while a non-oxidizing atmosphere is confined and maintained beneath the protective casing (42) by seals (55, 23, 47). The seals are placed on the one hand between the moving armature (15) and a first face (21) of the body (2) and on the other hand between the casing (42) and a second face (41) of the body which is opposite to the first face.

摘要： An electro-mechanical circuit breaker device incorporating a fuse cartridge, wherein two contact bars are normally connected by a series of mobile contacts held against their lower edge by springs, two in number for each. An insulating plate, suitably guided at its edges in the insulating envelope of the apparatus, receives the downward displacement that a coil applies by the Thomson effect to an aluminum disc, and it lowers the contacts against spring and latches them in open position by engagement of a bolt in a notch. The lower edge of the plate is provided with teeth to receive the successive contacts and retain them transversely, while each of the mobile contacts is notched to ensure lengthwise retention.

摘要： A miniature latching thermomagnetic relay is disclosed which offers high contact forces, small size, and low cost. Ferromagnetic material is placed upon heaters in a low thermal conductivity substrate. A permanent magnet beneath the substrate attracts a moving element above the substrate. Contact points on the substrate and the moving element from electrical connections.A control signal causes a heater to warm the ferromagnetic material, changing the saturation flux density of the material. This results in an unbalanced force on the moving element, causing it to rock about a pivot point to open or close connections as desired. Planar fabrication techniques may be used to construct the relay.
