ABSTRACT:
A magnetic bubble switch operates in a drive-to-transfer mode when a rotating magnetic field is applied. The switch has a magnetic element in the shape that defines the letter "Y" having two arms and a stem. The switch has at least one serration on the arm of the Y in the vicinity of the stem. The switch has a conductor which is positioned across the end of the stem of the Y. A magnetic element is positioned so as to form a gap with the stem of the Y.
