Electrical switching arrangement with improved linear bearing

#This application claims the benefit of German Patent Application No. 102015212801.6, filed Jul. 8, 2015.

#The invention relates to an electrical switch and, more particularly, to an electrical switch with a movable armature.

#Electrical switches, such as relays, are known in the art. Patents U.S. Pat. No. 6,911,884 B2 and U.S. Pat. No. 8,138,863 B2 each disclose an electrical switch having a solenoid, a movable armature, an armature shaft attached to the movable armature, a contact assembly with a plurality of contacts, and other components. The contact assembly is located in a switching chamber region such that any electrical arcs which may arise can be sealed off from an electromagnetic drive system. The contact assembly is attached to the armature shaft, which penetrates a covering plate at a contact chamber aperture. The armature shaft is attached to the armature such that a movement of the armature is also transmitted to the contact assembly.

#The invention will now be described by way of example with reference to the accompanying figures, of which:

#FIG. 1 is a sectional view of an electrical switch according to the invention;

#FIG. 2 is a detail view of the electrical switch of FIG. 1; and

#The invention is explained in greater detail below with reference to embodiments of an electrical switch. This invention may, however, be embodied in other different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and still fully convey the scope of the invention to those skilled in the art.

#An electrical switch 1, according to the invention, is shown in FIGS. 1 and 2. The electrical switch 1 has a solenoid assembly 3 and a contact chamber 5. As shown in FIG. 1, the electrical switch 1 extends in a width b, which is measured along an x-axis, a depth t, which is measured along a y-axis, and a height h, which is measured along a z-axis.

#The contact chamber 5, as shown in FIG. 1, has an upper housing 7 and a contact chamber plate 11, which together enclose an upper chamber 13. The contact chamber plate 11 has a contact chamber aperture 9 located approximately centrally on the contact chamber plate 11.
