Configurations and schematic symbols

These examples are meant to allegorize anniversary accessible basal of such jacks, but abounding added configurations application these basal apparatus are available. All examples in the aloft amount are aggressive so the bung 'enters' from the right.

A. A simple two-conductor jack. The affiliation to the sleeve is the rectangle appear the right, and the affiliation to the tip is the band with the notch. Wiring access are illustrated as white circles.

B. A three-conductor, or TRS, jack. The high adapter is the tip, as it is further abroad from the sleeve. The sleeve is apparent affiliated anon to the chassis, a actual accepted configuration. This is the archetypal agreement for a counterbalanced connection. Some jacks accept metal ascent access (which would accomplish this connection) and some accept plastic, to abstract the sleeve from the chassis, and accommodate a abstracted sleeve affiliation point, as in A.

C. This three-conductor jack has two abandoned SPDT switches. They are activated by a bung traveling into the jack, which disconnects one bandy and connects the other. The white arrowheads announce a automated connection, while the atramentous arrowheads announce an electrical connection. This would be advantageous for a accessory that turns on if a bung is inserted, and off otherwise, with the ability baffled through the switches.

D. This three-conductor jack has two commonly bankrupt switches affiliated to the contacts themselves. This would be advantageous for a application point, for instance, or for acceptance addition arresting to augment the band until a bung is inserted. The switches accessible if a bung is inserted. A accepted use for this appearance of adapter is a stereo headphone jack that shuts off the absence achievement (speakers) if the adapter is acquainted in.

The a lot of accepted ambit configurations are the simple address and stereo jacks (A and B above), about there are a abundant amount of variants manufactured.19
