An in-depth look at audio jack switches and configurations

The audio jack is a national standard connector with many uncertain primary uses besides providing basic audio connections. Based on familiarity with the wide variety of available equipment, including core count and switch selection, interior designers can flexibly utilize this knowledgeable, small and stable connection solution.
2.5mm or 3.5mm audio jacks are common in many machines and equipment such as smart phones, multimedia players, and high-fidelity audio equipment. For imaginative design teams, it can not only easily connect external speakers or mobile phone headsets, but also connect a variety of accessories to control other functions of the system. An example of this is a smartphone lever that configures the camera shutter release button. To master how to rationally use this port number with simple structure but various functions, we must first deeply analyze its internal structure, data signal connection and switch organization.
The audio jack can be used as a simple switchless connector, or it can be used for one or several switches that are turned on depending on the insertion of the power plug. Switch connectors are suitable for a variety of primary purposes, such as disconnecting internal structure speakers, checking the insertion of spare parts, or applying tuning. If a switchless connector is used, a dedicated audio jack switch IC can be used for accessory inspection. Although this type of IC can increase the bill of materials and project cost, it can provide a number of functions, such as switch chatter and key-press verification.
The audio jack specification model number provides available cable and switch components and indicates how to pair. For example, the CUISJ2-2531X-T audio jack is a thin surface mount connector with a choice of 2 or 3 cores and can be purchased in unswitched, single switch or full switch configurations.
