    Hi,
    What ac to dc switch would be needed to activate an MP3 Trigger?
    The MP3 trigger plays audio tracts. It has a trigger sensor (3.3-5.0vdc) that triggers audio tracts to play.
    When I turn on a switched outlet (120vac), i would like the ac to dc switch to send a signal to the MP3 Trigger.
    I will also have an LED light box (I believe its 10 or 20 watts) connected to this switched outlet.

    The MP3 Trigger is found below.
    Thank you Members

    It says the input is active low with internal pull-up. The easiest way is to use a 120 VAC relay to close a contact to pull the input low.

    Hi,
    Is there a specific 120VAC relay that you recommend?

    The smallest, lowest power thing you have access to. It must be an electromechanical relay; a solid state relay will not work in this applicatin.
