Powering up in the absence of a magnetic field (less than
BOP and higher than BRP) will allow an indeterminate output
state. The correct state is warranted after the first excursion
beyond BOP or BRP.
Bipolar switches may switch on removal of field but
require field reversal for reliable operation over temperature
range; latches will not switch on removal of magnetic field.
