    Hello, I am trying to make a small keyfob type wireless relay that will connect to a headphone jack to cut out the audio when the button on the keyfob is pressed. Has anyone ever seen one of these or have a place where I can look to build one from scratch. Thank you for your time.

    Sure.. There are TONS of keyfob controlled relay modules on ebay (starting at only a couple dollars and going way up based on complexity/need,etc..). Just use it to disconnect one lead of the jack.

    But don't those relays have a output voltage?

    EDIT: Also I cannot buy things off of EBay.

    A relay requires power on the "coil" side and then can switch signals (like an audio signal if needed or a light/motor,etc..) on the "contact" side. They are "dry" contacts in that no voltage is present ..ie no output voltage using your terms.

    Is amazon or any of the other hundreds of sites on the internet that carry these out of the question too?
    No need to spend over $20 USD for your needs.
