Hi list !

Here is my question : I'd like to simulate a finger pressing some keys on a real keyboard or any electronic switch (a TV remote controller, a cellular phone, a computer keyboard). So I'd like to know if there are existing devices to do this and that could easily be plugged to pd. In my idea, the device is plugged to the two poles of the button, and when pd sends it a specific message to the device, it lets the electricity pass.
If someone can help me by explaining how a such device is named ? I searched on www.interface-z.com but did not find which hardware would fit to my needs...

Thanks a lot !
And sorry for the english...
