What is a switched audio jack?
The audio jack is an industry-standard connector that has many potential uses in addition to providing basic audio connectivity. A switched connector is needed for purposes such as disconnecting internal speakers when headphones are inserted, to detect the insertion of an accessory, or if using an audio mixing board.
Is the red wire in or out?
Red: Hot Wire You will usually only see a red wire when an outlet is a 240-volt outlet or when a wall switch controls the outlet. In this case, when the switch is “on,” the red wire will supply power to the outlet instead of the black wire. Like black electrical wires, red wires are also hot or live wires.
How do you wire up a jack?
Connect each wire to the correct section of the jack, marked by color; there will be a spot for the red, green, yellow, and black wires. Secure the wires by tightening each screw. Mount the jack. Push the wires into the wall and position the jack over the hole.

How many pins does a mini DIN connector have?
The 4-pin Mini Din connector is the proper name for what is commonly referenced as an S-Video connector. The connector has 4 pins arranged in 2 rows, as well as a keying block to make certain the plug cannot be inserted improperly.
