Abstract
A magnetically adjustable relay which may have an internally positioned sealed contact system is disclosed wherein the switching element of the contact system is elongated and has one end affixed to an elongated ferromagnetic adjusting plate. The adjusting plate is attached to the coil body by means of torsional cross pieces or bars. The position of the adjusting plate within the coil body can be adjusted by means of an exteriorly applied magnetic field which deforms the cross bars.
Claims13
In an electromagnetic relay having a housing with a flexible switching element mounted therein, the switching element attached at one of its two ends to an elongated ferromagnetic adjusting plate, another of the switching element ends cooperating with a second contact element carried by the housing to form an electrical connection, the ferromagnetic adjusting plate being pivotable within the housing by application of an externally applied magnetic field, the ferromagnetic plate carried by the housing, the improvement of the ferromagnetic plate being suspended from the housing through torsion bar means, the torsion bar means forming at least one swivel axis about which the ferromagnetic adjusting plate is pivotable under the influence of the externally applied magnetic field, the torsion bar means being formed of a material which is bendable to a new positional state upon torsional rotation under application of the external magnetic field.
In a miniature relay having a switching element affixed to a carrier assembly, the carrier assembly carried by a relay housing interior thereof, the switching element being resilient and the carrier assembly being formed, at least in part, of a ferromagnetic bendable material, the carrier assembly including an adjusting plate, the improvement of the carrier assembly having a centrally disposed elongated adjusting plate portion, spaced parallel extending guide portions and torsion bar interconnections between the adjusting plate portion and the guide portions, the torsion bar interconnections projecting laterally of the adjusting plate centrally thereof along the longitudinal extent of the adjusting plate, the guide portions carried by opposed internal side walls of the housing, the torsion bars being bendable.
