 Figure 2.  Upper part of a jack

 

 Figure 3.  When the key is pressed, the jack is raised, and the plectrum touches the string and begins to bend. Then the plectrum plucks the string and causes it to sound. The jack hits the jack rail. When the player's hand is released from the key, the jack falls back down under its own weight, and the plectrum pivots backwards to allow it to pass the string.

 

 Figure 4.  French shove coupler. To the left: uncoupled keyboards. The depressed upper key lifts the jack A upwards. The depressed lower key lifts jacks B and C. To the right: The upper keyboard is coupled to the lower one by pulling the latter. The depressed upper key lifts the jack A upwards. The depressed lower key lifts jacks A, B and C.

 

 

 Figure 5.  Dogleg jack, English coupler system. When depressed, the upper key lifts the "dogleg" jack (jack A) upwards. The lower key lifts all three jacks A, B, and C.
