Abstract: An assemblage having a thermally insulating switch and a thermal insulator for constituting an electrical conductor passthrough through the thermal insulator. The thermal insulator insulates an inner space from an outer space, the assemblage having inner connector on the side of the inner space and outer connector on the side of the outer space, which are electrically conductively connectable by the switch. The assemblage has a control unit for controlling the thermally insulating switch, a current flowing through the switch is detectable by the control unit, the switch is controllable by the control unit in such a way that the switch is actuatable only in a substantially zero-current state, and the switch is disposed in the thermal insulator in such a way that thermal insulation between the inner connector and the outer connector is accomplished by way of the switch in the open state.

Abstract: A method for producing a gas sensor device for detecting a gaseous analyte includes providing a sensor body comprising a semiconductor substrate, in which a cavity section is shaped, and a solid electrolyte layer arranged at a surface of the substrate. The electrolyte layer is not covered by the substrate in the cavity section. The method includes producing a signal conductor layer deposited dry-chemically at a substrate side of the sensor body, such that, in the region of the electrolyte layer not covered by the substrate in the cavity section, a cutout section is shaped in the signal conductor layer, in which the signal conductor layer is removed or not deposited. The method includes applying measuring electrodes to the electrolyte layer by a wet-chemical process. One measuring electrode is arranged in the cutout section and one measuring electrode is arranged on an electrolyte layer side of the sensor body.
