Abstract
An adjustable flux generator used in conjunction with a Hall effect switch, comprising a coil and a magnetic circuit including an adjustable core. The coil produces a field of magnetic flux in response to the presence of an electrical current which is transmitted via the magnetic circuit to the Hall effect switch. The adjustable core is disposed to be manually adjusted to control the amount of magnetic flux delivered to the Hall effect switch. When the flux exceeds the Hall switch operate point the switch produces an output signal.
