Abstract
A crush sensor (10) includes a deformable first elongated member (20) having a width (W) and a length (L). A deformable second elongated member (30) has a width (W) and a length (L). The first and second members are parallel to each other and are closely spaced from one another. The first member includes an elongated contact surface (22) extending along its length. The second member includes an elongated contact surface (32) extending along its length and facing towards the elongated contact surface of the first member. The contact surface of at least one of the members includes a generally planar strip (34) and a raised electrically conductive rib (36) extending along its length and protruding from the strip toward the contact surface of the other member. The contact surfaces are normally electrically isolated from one another when the members are closely spaced from one another. The contact surfaces move into electrical contact with each other upon deformation of at least one of the first and second members.
