Rotary Interrupt Switch
The interrupt switch can be incorporated in applications of speed or position sensing, generally of rotat-
ing objects. The Rotary Interrupt Switch, in Figure 6, uses a toothed ring to interrupt the magnetic field
reaching the Hall IC. When a solid piece of steel (ferrous vane) blocks the magnetic field, the switch turns
OFF. During the gaps, or spaces in the steel, the South magnetic pole turns ON the switch. This is the sys-
tem commonly used for automotive ignition and many industrial applications, where accurate position is
critical.
Figure 6, Rotary Interrupt Switch
Figure 6 uses a notched
interrupter on a rotating
shaft to activate the device.
