| 摘要 |
The invention relates to a pressure-responsive sensor unit (10). In order to provide means for detecting pressure fast and reliably which allow for design flexibility and easy assembly, the sensor unit (10) comprises at least one membrane switch sensor (11), which comprises a first carrier foil and a second carrier foil spaced from each other by a spacer foil, said spacer foil having therein at least one opening defining a pressure-responsive sensor cell (12), and at least two electrodes arranged in facing relationship with each other in said cell (12) on said first and said second carrier foil, respectively, in such a way that they are brought closer together when pressure is applied to the membrane switch sensor (11), wherein at least one activator element (14), adhered to an outer surface (13) of the membrane switch sensor (11), forms a raised structure of substantially stable form on said outer surface (13), at least partially over one sensor cell (12). |
