Abstract
The invention relates to a switch strip (10) for an apparatus for detecting an obstruction (210) in the movement range (221) of a closure element (220), in particular of an automotive vehicle (200). The switch strip (10) has an inner electrode (20), an outer electrode (30) approximately concentrically surrounding the inner electrode (20) at a distance (D), and a space (40) filled with air, which is arranged between the outer electrode (30) and the inner electrode (20) and which is dielectric. Furthermore, the switch strip (10) has a spacer (50) which is deformable in a direction transverse to the longitudinal direction. The spacer (50) spaces and insulates the two electrodes (20, 30) from one another. The outer electrode (30) is deformable by a force (F) applied from the outside. The deformation of the outer electrode (30) is able to at least in portions bring the inner electrode (20) and the outer electrode (30) into contact with each other. Such a switch strip (10) is also referred to as a tactile switch strip (10).
