Abstract

An improved horizontal crossbar multiswitch utilizes a modified armature assembly comprising several component parts that cooperate when the bar is in a rest position to provide a magnetic field of minimum reluctance in cooperation with an associated electromagnet, and when the bar is in an operating position provide a magnetic field of maximum reluctance by increasing the gap existing between the associated electromagnetic coil and one of the armature component parts. This arrangement prevents the armature from being further energized when the crossbar is in a rotated state by means of reduction in the magnetic forces associated with the high reluctance gap and further provides electrical indication of the operative position of the armature.
