ABSTRACT:
A magnetically operated switch especially useful in telephone applications includes a transformer having a plurality of windings on an E-frame core and a reed switch magnetically coupled to the core by a plurality of high permeability strips which are placed in juxtaposition with the core and which have rolled end portions for supportably receiving the reed switch. The switch may be used in a hybrid junction for dial pulse detection.
