  • Patent number: 4156191
    Abstract: A method and apparatus for setting the relative magnetic relationship between a Hall Effect switch with a given operating field strength and a permanent magnet to operate the switch and having a magnetic field with a field strength greater than the operating field strength. This invention can be used for adjusting the toggle point of a combined Hall Effect switch and magnet or the dwell between the operate point and release point of the switch. This method or apparatus comprises the steps of determining the actual switching point or dwell of a combined Hall Effect switch and operating magnet, which switching point or dwell is controlled by the combination of the field strength of the magnet and the operating field strength of the switch, determining the difference between the actual switching point or dwell and a desired switching point or dwell and then modifying the magnetization of the permanent magnet to shift the actual switching point or dwell toward the desired switching point or dwell.
