摘要

A resilient intermediate section (12) is arranged inside the hollow cavity (11) of a resilient section (14) of essentially triangular cross-section. The intermediate section (12) has a flat base portion (15) which contacts the base surface (13) of the resilient section (14) and a switching strip (18) is arranged on the flat base portion (15). In addition the intermediate section (12) has limbs (16) which extend into the tapering hollow cavity (11) and encloses the sides of the switching strip (18). If the section (14) bends due to contact with an obstacle then the limbs (16) are respectively acted on by further arching of the side surfaces (17) and act in turn via inwardly directed actuating ribs (20) on the surface of the switching strip (18) which faces the apex edge (19) of the resilient section.
