<p>The device is especially made of sheet metal (3) with at least one deformation region (14) with a deformation field and connecting bridges with free fields between them. The deformation field is at least partly connected to the surrounding metal plate by the bridges, which are shaped and/or arranged to stretch or change position when pressure is applied to the deformation field, which thus remains protruding from the surrounding metal sheet.</p> |
