    Hello Given,

    So your are asking for a 1:1 2channel switch like this

    1.Does it need to  support a 7.5V supply voltage(VDD) or 7.5V signal (source to drain)?

    2. Does this device need to support 1Amp current through the signal path or survive 1amp current fault situtaion?

    Regards,

    As far as I understand, a DPDT switch has two 1:2 channels:

    Normal switches are designed to handle analog and digital signals, and small loads; they cannot handle 1 A.

    What is your application? There is no integrated device that has four 1 A I/Os. If you want to switch between two power sources, you might be able to use two power muxes like the TPS2124. The most general solution would be to use four load switches like the TPS22810.
