A cancel switch is intended for use with a vehicle equipped with an audiovisual system having a compulsory switching unit which compulsorily switches a video on a monitor screen to a still image or a navigation screen during a running condition of the vehicle. The cancel switch includes a deactivation unit deactivating the compulsory switching unit so that the video is displayed even during the running condition of the vehicle. The deactivation unit includes a proximity sensor which detects proximity of an object by a non-contact manner and a switching circuit which conducts or breaks a signal line through which a determination signal indicative of the running condition of the vehicle is transmitted.
