Abstract:

A control for raising and lowering a lift axle ( ) on a motor vehicle ( ) having an ignition switch ( ) for turning the motor on and off. The control has a circuit ( ) that is fed through the ignition switch when the ignition switch is on but not when the ignition switch is off and that has a first switch device ( F) that requires actuation to enable the lift axle to be lowered and a second switch device ( D) that, once the first switch device has been actuated to enable the lift axle to be lowered, is effective upon being actuated to cause the lift axle to be lowered. Placement of the vehicle transmission in reverse automatically raises the lift axle if it has been lowered.
