Abstract :
Magnetic cores of fairly rectangular hysteresis loop material are used as a trigger device. Magnetic fluxes are used instead of electrical currents to indicate the two stable positions of the tigger. This paper shows how the magnetic flux level may be detected without a mechanical motion. The construction and functioning of several types of such magnetic triggers are discussed.
