Abstract

A gas spring comprises a cylinder 2 and a piston rod 3, and defines an electrically conductive path included in an electrical circuit. A switch in unit the gas spring selectively opens and closes the conductive path according to the direction of relative movement of the piston rod and cylinder. The switch unit comprises a contact piece 9 which is in frictional and electrically conductive engagement with the internal sliding surface 2a of the cylinder 2. This contact piece 9 is axially movable with respect to the piston rod 3 between two terminal positions. In a first terminal position during outward movement of the rod 3 (as shown) the contact piece 9 closes the electrically conductive path by abutting the surface 11 of a conductive piston disc 7. In a second terminal position during inward movement of the rod 3, the contact piece 9 abuts the surface 12 of an insulating piston disc 8 and thus opens the electrically conductive path. The contact piece may be in frictional engagement with the rod as at 25 rather than the cylinder, the contact piece then engaging either insulating member 26 or projection 27. The unit is useful for switching an anti-theft device for a boot lid.
