Abstract
Abstract A mosaic arrangement of switch elements, especially electrical push-button switches with quadratic or square switch bodies, arranged at the front surface or side of electrical switch panels and the like, wherein the switch bodies possess at their edge corners extending perpendicular to the front surface of the switch panel recesses which at least over a portion of the length of the corners are constructed as guide grooves, and wherein at least partially at the crossover locations or intersection of the mosaic arrangement of the switch elements, there are provided coupling elements having four corner noses each of which engages in the guide groove of a respective switch body for insertion in the neighboring recesses of the switch bodies bounding at such crossover or intersection locations.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
A mosaic arrangement of switch elements, especially electrical push-button switches with substantially quadratic switch bodies arranged at intersection locations at the front surface of an electrical switch panel and the like, the improvement wherein each of the switch bodies are provided with recesses at their edge corners extending substantially perpendicular to the front surface of the switch panel, each of said recesses being constructed over a portion of the edge corner length as guide grooves, and at least partially at the intersection locations there are provided coupling elements, each coupling element having four corner noses, said four corner noses extending into respective recesses of switch bodies neighboring one another at an intersection location and engaging with respective guide grooves of said neighboring switch bodies for interlocking to one another said neighboring switch bodies, each coupling element being provided with an axial throughpassage bore for receiving an associated attachment means for securing the switch bodies which are interlocked by such coupling element to the electrical switch panel.
Claim 2
Dependent Claim
166 words
A mosaic arrangement of switch elements, especially electrical push-button switches with substantially quadratic switch bodies arranged at intersection locations at the front surface of an electrical switch panel and the like, the improvement wherein each of the switch bodies are provided with recesses at their edge corners extending substantially perpendicular to the front surface of the switch panel, each of said recesses being constructed over a portion of the edge corner length as guide grooves, and at least partially at the intersection locations there are provided coupling elements, each coupling element having four corner noses, said four corner noses extending into respective recesses of switch bodies neighboring one another at an intersection location and engaging with respective guide grooves of said neighboring switch bodies for interlocking to one another said neighboring switch bodies, each coupling element being provided with an axial throughpassage bore for receiving an associated attachment means for securing the switch bodies which are interlocked by such coupling element to the electrical switch panel.
Claim 3
Dependent Claim
58 words
The arrangement as defined in claim 1, wherein the guide grooves in the recesses of the switch body are only partially provided thereat but centrally of the associated edge corner length for forming projections, and wherein the coupling elements possess at one side of the projections of the recesses of the switch bodies shoulders cooperating with said projections.
Claim 4
Dependent Claim
31 words
The arrangement as defined in claim 2, wherein the guide grooves in the switch bodies and the corner noses engaging therein of the coupling elements possess a substantially circular sector-shaped cross-section.
Claim 5
Dependent Claim
126 words
The combination of at least two switch elements and a coupling element for releasably interlocking said two switch elements with one another, each switch element comprising a switch body having an edge region, said edge regions of said two switch bodies being located adjacent one another, each of said edge regions being provided with recess means extending in the lengthwise direction of its switch body, each of said recess means having guide groove means, each coupling element having at least two corner noses, said coupling element, when interlocking said two switch elements with one another, having a respective nose seated in a respective recess means of a switch body and extending into the groove means thereof for releasably interlocking said two switch bodies to one another.
Claim 6
Dependent Claim
126 words
The combination of at least two switch elements and a coupling element for releasably interlocking said two switch elements with one another, each switch element comprising a switch body having an edge region, said edge regions of said two switch bodies being located adjacent one another, each of said edge regions being provided with recess means extending in the lengthwise direction of its switch body, each of said recess means having guide groove means, each coupling element having at least two corner noses, said coupling element, when interlocking said two switch elements with one another, having a respective nose seated in a respective recess means of a switch body and extending into the groove means thereof for releasably interlocking said two switch bodies to one another.
Claim 7
Dependent Claim
26 words
The combination as defined in claim 4, wherein each said recess means extends substantially over the entire length of the edge region of its switch body.
Claim 8
Dependent Claim
62 words
The combination as defined in claim 4, wherein each guide groove means has a projection means at an upper end thereof, said coupling element being provided with shoulder means bearing against said projection means when said coupling element interlocks said two switch bodies in order to limit the extent of insertion of the noses of the coupling element into said recess means.
