Abstract (en)
[origin: WO0070914A2] A shielded magnetic reed switch provides a magnetic reed switch disposed within a ferrous metal housing so that the ferrous metal housing shields the magnetic reed switch from magnetic flux. The shielded magnetic reed switch of the present invention remains unactuated until the ferrous metal housing is fully saturated and the magnetic flux required to actuate the magnetic reed switch is available within the ferrous metal housing. The present invention further provides a sensor for detecting the presence of an approaching magnetic field source at a predetermined distance between the shielded magnetic reed switch and the approaching magnetic field source.
