I am currently working on a project where I have two GSM modules in a single product. Those modules have each one a mic port and speaker port.
They will not be used simultaneously but they will be both including on the PCB of the device. I need to be able to switch automatically from one module to the other one depending on the gsm network availability. However, our customer have only one mic plug 3.5mm jack and one speaker plug 3.5mm jack.
Hence I need to connect this only plug (one for mic and one for speaker) to a kind of switch to redirect the signal properly to the module which is currently used (face to gsm network availability).
I am a bit confused by which device to use to perform this 'audio switch"
If anyone has idea about the component that woudl be best suited for this...?
but only one jack plug for eacc (one jack for mic, one jack for speaker)
