Function
The version without step display (and without slider) has two
buttons left and right for calling up the next or previous step
and a button in the centre. By pressing the right / left button
a few times one reaches the next higher or lower step. The
button in the middle returns the step switch to the bottom
step (= "Off"). The icon in the middle can be animated during
adjusting.
The version with step display (with slider) has a button to
reset the step switch (= off) and buttons to call up the next or
previous step. In addition, it uses a slider to show which step
is currently on. The slider cannot be operated. The icon in
the middle can be animated during adjusting.
