I want to install a wireless door chime, but the buttons that are available for them are pretty ugly. Is there a way to hook up a 'wired' doorbell button to the wireless transmitter? I assume both have just a momentary switch. Can I just crack the case for the wireless transmitter and wire the switch for the 'wired' button to it? That way I can embed the wireless transmitter in the wall and only show the nice looking button.
