Abstract
An apparatus or installation comprises a surface () and at least one piezoelectric sensor device () that is a piezoelectric touch switch comprising at least one piezoelectric sensor (), located below the surface () so that the surface () functions as an overlay to the piezoelectric touch switch, the piezoelectric sensor device () configured so that the piezoelectric sensor () bends in response to a force or pressure exerted on the surface () causing the surface () to bend. The apparatus () or installation comprises continuously adjustable compression adjusting means () that operate on the backer piece () to compress the piezoelectric sensor device () and the at least one squeezer () between the overlay () and the backer piece (), for compensating the surface or mounting tolerances.
