发明名称 Ignition switch-activated message system
摘要 A message actuating system for automobiles includes a key operated ignition switch which is movable between a first position and a second position, the automobile ignition system being operative when the ignition switch is in either the first or second position. A message device, such as a tape player with a prerecorded message, is activated when the switch is in the first position. The message device is selectively deactivated, and the tape rewound, when the switch is turned to the second position.
