    Sorry, can't edit the title, which should have referred to aux Input!

    Anyway, I'm trying to source a suitable single switch with which to separately provide the aux phono input on my Technics SU V3 amplifier from three different devices ie TV, cd player and a Roberts RS1 Streamer.

    I believe I need a double pole triple throw type of switch, but there doesn't appear to be much of that type available. All I have found is a slide switch which is described as on-on-on, for 12v dc max at 200mA max. Trouble is I'm unsure whether this is up to the job in terms of V & A, and also its described function, and it's not available until April. A 100ma one is in stock - could this be suitable?

    A similarly rated one is available in on-off-on configuration, but I don't think this will suit. The former is shown on website below.

    Any advice gratefully received. Thanks.

    A 2 pole 3 way rotary switch would be better.

    Are you trying to achieve this?,more inputs to one AUX input?.
    Then as already suggested, a two pole 3 (or more) way rotary switch.

    Thanks for all replies.
    The Amazon unit is really neat, Martin, but I really only need the switch itself to replace an existing two way switch.
    Rotary switch idea seems much more robust, but I'm still not sure what V & mA to go for?

    That is good advice if you’re switching grounds.

    It also avoids connecting to sources together.

    Wouldn’t a ‘make before break’ connect two sources together?.
    I would have thought a ‘break before make’ would be suitable for signal path.

    You are right. That's what I intended to say but got it back to front. See the switch I recommended.
