A box-frame housing for the installation of electronic modules has frame elements and side walls and provides a subdivision into sub-regions, which are limited by dividing walls. The frame elements and the side walls and the dividing walls provide at least one recess and/or at least one edge projection. A projection engages in a recess and both are connected to one another by welding.

A box-frame housing for the installation of electronic modules has frame elements and side walls and provides a subdivision into sub-regions, which are limited by dividing walls. The frame elements and the side walls and dividing walls provide at least one recess and/or at least one edge projection. A projection engages in a recess and both are connected to one another by welding.

A locking system for fitting and securing modules in a housing includes at least one module, which is surrounded by a chassis and provides a plug connection at a rear side. The front side of the module disposed opposite to the rear side provides a chassis front-plate connected to the chassis. Each module can be locked by a snap-in locking device in a housing, into which the module is pushed. In order to release the snap-in locking device, an opening tool engages in the chassis front-plate. A pulling stress can be exerted on the chassis front-plate by the opening tool, and the module can be withdrawn from the housing.

Locking system for modules within a housing and a method for fitting

Electrical switching device, especially a high-frequency switching device, with at least one oblong electrical switching element, which is arranged with one contact end between two fixed-contact elements spaced a transverse distance from one another and can be moved by two adjustment elements forming a transverse movement drive transversely to a longitudinal direction optionally towards the one or the other fixed-contact element. The adjustment elements are disposed laterally alongside the switching element and can be moved transversely to and from the switching element. In order to improve the transverse movement drive for the switching element, the switching element-comprises magnetic material, wherein the adjustment elements are formed by magnets.

Electrical switching device comprising magnetic displacement elements for a switching element

An electrical switching device, especially a high-frequency switching device, comprising an elongate electrical switching element, a contact end of which is disposed between two opposite contact elements that are transversally spaced apart from each other. The switching element can be selectively moved perpendicularly to the longitudinal direction thereof towards one or the other opposite contact element by two adjusting elements that are located on both sides next to the switching element. In order to eliminate or at least reduce frictional processes and the risk of the electrical contact being damaged by abrasion, the switching element is made at least in part of magnetic material while the adjusting elements are formed by two magnet assemblies, the magnetic force of one magnet assembly or the other magnet assembly being selectively reducible or increasable.
