Two-layer Medium/Large Slider Or Wheel
Introduction
Slider
When construcing two-layer medium/large sliders and wheels the electrodes are constructed from
slanted “segments”.
For a slider, each “segment” is 4 mm high, and the slider is constructed from as many segments as is
necessary to obtain the required height, as shown in
direction of the slant of the “segments” alternates in
Figure 6-6.
