1476508 Mechanical switches MOULTON DEVELOPMENT Ltd 23 June 1975 [2 July 1974] 29300/74 Heading H1N [Also in Division B7] Actuating mechanism for a pair of switches 71, 72 controlling operation of a vehicle suspension levelling system comprises a spring leaf 75 oscillated about a pivot axis at one end by a fork 78 which acts on the other end of the leaf and is connected to the central region of a torsion bar 70 linked to suspension arms 14 carrying the rear wheels of a vehicle, and an hydraulic damper 76 arranged to damp osoillation of the leaf so that when the torsion bar 70 rotates the leaf 75 resiently deforms and one of the switches 71, 72 is actuated by the leaf only when the movement of the bar 70 exceeds a predetermined amount for a predetermined time interval. In another embodiment the spring leaf is replaced by a torsion spring which is twisted to actuate the switches.
