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.
