A microphone having a housing that includes a bottom part and an upper part, and a transducer element arranged in the housing and which is electrically and mechanically connected to the bottom part. For stress-free mounting of the transducer element, a flexible connecting element is proposed, which is pliable and/or compressible, is arranged between the transducer element and the upper part, and connects the transducer element to the upper part. The connecting element includes a plastic, in which gas bubbles are distributed, the gas bubbles having a volume fraction of between 50 and 98% in the connecting element.

A contact device for an electrical switch, and an electrical switch are disclosed. In an embodiment the contact device includes a first connection element, a second connection element, a movable contact bridge, at least two magnets configured to quench arcs which arise during a switching of the electrical switch, wherein the magnets are configured to generate a magnetic field in a first region which comprises at least one first contact region and one second contact region, in which, when the electrical switch is in a closed switching position, the first connection element and the second connection element are in contact with the contact bridge and at least one deflection element configured to distort the magnetic field such that a first arc when formed between the first connection element and the contact bridge, and a second arc when formed between the second connection element and the contact bridge, are forced into different directions, pointing away from each other.

A multi-step tube () of a ceramic material comprises a tube body () of the ceramic material having an inner wall () located inside the tube body (). A surface of the inner wall () is formed with a plurality of steps (). The steps () are formed to extend differently far inside the tube (). A multi-layered gas discharge tube comprises the multi-step tube (). An inner electrode () is disposed on a step (), and an outer electrode () is disposed on an outer surface () of the tube body (). A disc () is partially placed on a step () and the inner electrode () between the inner electrode () and the outer electrode () so that, in case of an electrostatic discharge, the discharge will only take place in the center of the multi-step tube () and not at the border of the isolated ceramic disc ().

A spark gap arrangement includes a discharge chamber, an electrode head and a contact connection arranged outside the discharge chamber. The electrode head is electrically conductively connected and mechanically coupled to the contact connection in such a way that, when the contact connection is removed from its position or when the contact connection reaches a preset position, the electrically conductive connection is interrupted, and the electrode head is mechanically decoupled from the contact connection so that the electrode head is movable in the direction of the discharge chamber interior and/or within the discharge chamber.

A surge arrester includes a short-circuit device. The short-circuit device includes at least one first base element. The first base element is rigidly connected in an electrically conducting and mechanical manner to a first electrode of the surge arrester. The short-circuit device also includes at least one spring arm arranged on the base element. The free end of the spring arm has a distance to the base element, and the spring arm extends over at least two adjoining electrodes of the surge arrester.
