Rotary Slide-by Switch
Figure 7, Rotary Slide-by Switch
The Rotary Slide-by Switch in Figure 7 is generally used to measure rotary speed to synchronize switch-
ing with position. The Hall IC is activated by a rotating magnet. When the South pole passes by the Hall
IC, the IC is switched ON. As the North pole passes, the Hall IC is switched OFF. The solid circular mag-
net, shown in Figure 7A, is called a Ring Magnet. A ring magnet has alternating North and South poles.
Ring magnets may have from two poles to thirty-six or more, depending on size. Graph 1, below illus-
trates the transition between North and South polarity at various air gaps. Notice the transition point is
similar at the various gaps.
