Hollow profile for an electrical switching strip and method for detecting obstacles with an electrical switching bar

The invention relates to a hollow profile for an electrical switching strip, being provided adjacent to a through-going in the longitudinal direction of the elastic hollow section cavity of the hollow profile at least a first and a second electrical conductors at a compression of the hollow profile by a to be detected obstacle at least in sections in contact with each come and are spaced apart in a non-compressed state of the hollow profile, wherein at least one is seen at the cavity adjacent the region of the at least one first and / or second conductor in a sectional view perpendicular to the longitudinal direction are arranged offset relative to a center plane of the hollow profile.
