What is it?

This is a stereo audio switcher which allows:

• switching one 3.5mm input between two 3.5mm outputs, or
• switching one 3.5mm output between two 3.5mm inputs

See the images for usage diagrams.

Why did you make it?

Sometimes I don't want to turn my desktop PC on just to be able to listen to music. With this audio switcher I can connect both my desktop PC and my mobile phone to the same speakers and simply switch between the two of them as required!

What makes it special?

It also works in reverse, connect one audio source to two different outputs e.g. headphones and speakers and easily switch between the two of them!

Some audio switchers use a common ground which can introduce an audible hum, others combine the left and right channels for mono audio. Using a 3PDT toggle switch means that the left, right and ground signals are all isolated and independently switched.

The PCB has also been designed so that the toggle-switch points in the direction of the selected audio source/destination for care free switching!

What's left to say?

Size is approximately 4cm x 4cm x 4cm (1.5inch x 1.5inch x 1.5inch).

You will get:

Choose from partially assembled or fully assembled:

Partially assembled option: This contains:

• a PCB
• 3 3.5mm audio jacks (pre-soldered)
• 3PDT toggle switch (unsoldered)

Fully assembled option: As above, but fully assembled and ready to go.

Note: Due to the size of the switch, the increased cost for this option is due to postage.
