Method and apparatus for connecting to a circuit in a jack without interrupting the circuit
First Claim
1. A method of connecting to a circuit in a jack, the jack having a port adjacent to the circuit, the circuit comprising first and second switch contacts that are normally closed together so as to provide continuity of the circuit, the first switch contact being displaceable to first and second displacements relative to the second switch contact, with the circuit being closed when the first switch contact is displaced to the first displacement due to the first switch contact being in contact with the second switch contact, and with the circuit being opened when the first switch contact is displaced to the second displacement due to the first switch contact being out of contact with the second switch contact, comprising the steps of:
- a) providing a conductor with at least one surface that, when the one surface contacts the first switch contact, limits the displacement of the first switch contact to the first displacement so as to maintain circuit continuity through the first and second switch contacts;
b) inserting the conductor partially into the port of the jack;
c) rotating the conductor about a longitudinal axis so as to align the one conductor surface with the first switch contact;
d) continuing to insert the conductor fully into the port of the jack and limiting the displacement of the first switch contact to the first displacement during contact with the conductor so as to maintain circuit continuity through the first and second switch contacts.

Abstract
In a jack that receives a "make with break" plug or jack, there is provided a "make without break" plug. The jack has a circuit with a set of contacts that are normally closed. The circuit is opened by displacing one of the contacts out of contact with the other contact. With the make without break plug, only a minimal displacement of the jack contacts occurs. The plug minimizes the displacement of the jack contacts by limiting the physical size of the plug. A preferred embodiment utilizes a reduced radius to form a notch in the plug. This notch receives the jack contacts with little or no displacement of these contacts. Another technique used to minimize the displacement of the jack contacts is to limit the amount of force exerted by the plug against the jack contacts. The plug itself is provided with displaceable and pliant contacts. Less force is required to displace the plug contacts than is required to displace the jack contacts.

5. A plug for insertion into a jack, the jack having a set of normally closed contacts therein, comprising:
-
a) a sleeve having an outside diameter, the outside diameter being formed by a sleeve radius, the sleeve being structured and arranged to be received by a port in the jack, the sleeve having an end; b) a conductor that extends from the end of the sleeve, the conductor having a free end and a sleeve end, with the sleeve end of the conductor being connected to the sleeve, the conductor having a length, the conductor being offset from a longitudinal axis of the sleeve so as to form a notch that extends from the free end along the length of the conductor toward the sleeve end.

7. An apparatus for connecting to a circuit, comprising:
-
a) a jack, the jack having a port and comprising first and second switch contacts that are normally closed together so as to provide continuity of the circuit in the jack, the first switch contact being displaceable to first and second displacements relative to the second switch contact, with the circuit being closed when the first switch contact is displaced to the first displacement due to the first switch contact being in contact with the second switch contact, and with the circuit being opened when the first switch contact is displaced to the second displacement due to the first switch contact bring out of contact with the second switch contact; b) a plug comprising a sleeve for being received by the jack port, the plug also comprising a conductor extending from the sleeve, the plug conductor comprises a first surface, the first surface having a first radius with respect to a longitudinal axis of the sleeve, the first surface extending from a free end of the conductor toward the sleeve, wherein when the first surface contacts the first switch contact, circuit continuity through the first and second switch contacts is maintained during the insertion of the plug conductor into the jack port. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
