<p>A shift switch control device for selection lever units of automatic transmissions is disclosed. The shift switch control device has a selection lever (9) for selecting a desired range within a transmission pattern during the automatic transmission mode (1) and performing an up- or down-shifting operation during the manual transmission mode (3). A rotary lever (13), having a key slot (19), is positioned in the gap between the up- and down-shift switches, while a locking key (33) is inserted into the key slot so as to lock the rotary lever to the selection lever at the M-stage of the manual transmission mode. A key actuation rod (47) is set within the casing (29) of the selection lever such that it rotates the locking key to the outside or inside of the casing of the selection lever. In the shift switch control device, the actuated direction of the actuation buttons of the two shift switches (5,7) is equal to that of the rotary lever, thus accomplishing a desired operational reliability of the shift switch control device during a manual transmission mode. The control device is also reduced in the number of its parts, thus being preferably simplified in its construction and being easily manufactured at a low production cost, and being easily installed within a limited area. <IMAGE></p> |
