Abstract
Abstract A transducer device having a primary winding, a plurality of secondary windings and a core electrically coupling the secondary windings with the primary winding. The secondary windings comprise a plurality of insulated wires bundled together and wound as a helical winding so that when an input signal is applied to the primary winding a separate output signal is induced in each of the secondary windings.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A transducer device comprising a primary winding for receiving an input signal, a secondary winding, a fixed core of magnetic material electrically coupling the primary winding and the secondary winding, said secondary winding including a plurality of separate wires which are bundled together and insulated from each other so that a plurality of separated output signals are provided from a single input signal, and a key member of metallic material secured for being moved with respect to said core for switching the output signal of each of said wires from a lower value to a higher value.
Claim 2
Dependent Claim
97 words
A transducer device comprising a primary winding for receiving an input signal, a secondary winding, a fixed core of magnetic material electrically coupling the primary winding and the secondary winding, said secondary winding including a plurality of separate wires which are bundled together and insulated from each other so that a plurality of separated output signals are provided from a single input signal, and a key member of metallic material secured for being moved with respect to said core for switching the output signal of each of said wires from a lower value to a higher value.
Claim 3
Dependent Claim
36 words
A transducer device in accordance with claim 1 including a cylindrical bobbin of an electrical insulating material, the primary winding and the secondary winding being wound around the bobbin and the core extending through the windings.
Claim 4
Dependent Claim
28 words
A transducer device in accordance with claim 2 in which the bobbin has a hole extending longitudinally therethrough along its axis and the core is within said hole.
Claim 5
Dependent Claim
36 words
A transducer device in accordance with claim 3 in which the bobbin has a plurality of annular grooves in its outer surface and each of the windings is wound in a separate one of said grooves.
Claim 6
Dependent Claim
45 words
A transducer device in accordance with claim 4 in which the bobbin has three annular grooves in its outer surface, one of said windings being wound in the center groove and the other of said windings being wound partially in each of the end grooves.
