Panel-mounting jacks are generally provided with about-face contacts. A lot of commonly, a address jack is provided with one frequently bankrupt (NC) contact, which is affiliated to the tip (live) affiliation if no bung is in the socket, and broken if a bung is inserted. Stereo sockets frequently accommodate two such NC contacts, one for the tip (left approach live) and one for the ring or collar (right approach live). Some designs of jack aswell accept such a affiliation on the sleeve. As this acquaintance is usually ground, it is not abundant use for arresting switching, but could be acclimated to announce to cyberbanking chip that the atrium was in use.
Less commonly, some jacks are provided with frequently accessible (NO) or change-over contacts, and/or the about-face contacts may be abandoned from the connector.
The aboriginal purpose of these contacts was for switching in blast exchanges, for which there were abounding patterns. Two sets of change-over contacts, abandoned from the adapter contacts, were common. The added contempo arrangement of one NC acquaintance for anniversary arresting path, internally absorbed to the adapter contact, stems from their use as headphone jacks. In abounding amplifiers and accessories absolute them, such as cyberbanking organs, a headphone jack is provided that disconnects the loudspeakers if in use. This is done by agency of these about-face contacts. In added equipment, a copy amount is provided if the headphones are not connected. This is aswell calmly provided by agency of these NC contacts.
Other uses for these contacts accept been found. One is to arrest a arresting aisle to accredit added chip to be inserted. This is done by application one NC acquaintance of a stereo jack to affix the tip and ring calm if no bung is inserted. The tip is again fabricated the output, and the ring the ascribe (or carnality versa), appropriately basic a application point.
Another use is to accommodate another address or stereo achievement accessories on some guitars and cyberbanking organs. This is accomplished by application two address jacks, one for larboard approach and one for right, and base the NC acquaintance on the appropriate approach jack to the tip of the other, to affix the two adapter tips calm if the appropriate approach achievement is not in use. This again mixes the signals so that the larboard approach jack doubles as a address output.

A accepted stereo jack is acclimated on a lot of battery-powered guitar furnishings pedals to annihilate the charge for a abstracted ability switch. In this configuration, the centralized array has its abrogating terminal active to the sleeve acquaintance of the jack. If the user plugs in a two-conductor (mono) guitar or microphone lead, the consistent circumlocute amid sleeve and ring connects an centralized array to the unit's circuitry, ensuring that it admiral up or down automatically whenever a arresting advance is amid or removed. A check of this architecture is the accident of aback absolution the array if the advance is not removed afterwards use, such as if the accessories is larboard acquainted in overnight.
