Slightly more complicated was the two axis stepping switch, (also called Strowger switch or two motion selector in Britain). Typically, a single compact group of wipers could connect to one of 100 (or 200) different fixed contacts, in ten levels. When the switch was idle, the wipers were disengaged from the fixed contacts.
The Strowger switch is the first commercially successful electromechanical stepping switch telephone exchange system. It was developed by the Strowger Automatic Telephone Exchange Company founded in 1891 by Almon Brown Strowger.

During, the pressure rise,F-R clutch is in energized condition which makes the vehicle to move forward/Reverse direction. Flow to tank line is blocked during the flow to F/R clutch. Power shuttle are incorporated in transmissions in three forms: counter-shaft , full planetary (power shifts) , and CVT transmissions .
The forward/reverse lever on Caterpillar tractors is also called a Johnson bar. Some light general aviation aircraft (including Piper Cherokees, Beech Musketeers, and some early model Cessnas—such as the Cessna 140)—use Johnson bars to actuate flaps and wheel brakes.
