Abstract
Circuits, methods, and apparatus that may provide for reliable detection of electrical and optical audio plugs. One example may detect an optical audio plug by employing one or more mechanical detect switches. These switches may include a first contacting portion and a second contacting portion that are separated from each other when an audio plug is inserted into the audio jack. The second contacting portion may include one or more arms to contact a surface portion of the first contacting portion. The first contacting portion and the second contacting portion may be biased such that they tend to stay in contact with each other as the first contacting portion begins to be deflected by the insertion of an audio plug, thereby wiping dust or debris from between the first contacting portion and the second contacting portion.
