Abstract: A remote control device for an automotive vehicle wherein a transmitter (10) is received in a holder (2), with side-marker lights and taillights staying on, to connect holder-side contacts (3, 4) to transmitter-side contacts (16, 17), and the transmitter (10) is removed from the holder (2) to disconnect the transmitter-side contacts (16, 17) from the holder-side contacts (3, 4). A differentiating circuit (21) detects the disconnection of the transmitter-side contacts (16, 17) from the holder-side contacts (3, 4) by the removal of the transmitter (10) in the on position of the side-marker lights and taillights, and a timer (22) clocks a predetermined timer time over which LEDs illuminate manipulation keys (12) of the transmitter (10). Only the removal of the remote control transmitter from the holder permits the manipulation keys to be readily illuminated.

Abstract: A recess portion 14a is formed in the underside of the flange 14 of a tilting holder 13 at a position corresponding to, for example, an "upper right" select switch 4. As a result, the operating pin 10 of the "upper right" select switch 4 has a fixed gap with the flange 14. Consequently, the operating pin 10 of the "upper right" select switch is pressed when an operating lever 15 is tilted. However, the operating range B of, for example, the "upper right" select switch 4 is set narrower than the operating range A of, for example, the "upper" select switch 4 since the pressing of the operating pin 10 of, for example, the "upper right" select switch 4 is delayed by the gap resulting from the recess portion 14a.
