A shift switch control device for selection lever units of automatic transmissions is disclosed. The shift switch control device has a selection lever for selecting a desired range within a transmission pattern during the automatic transmission mode and performing an up- or down-shifting operation during the manual transmission mode. A rotary plate is provided at the selection lever, and has up- and down-shift switches at its top end, with a projection provided at the central portion of the rotary plate. A manipulation lever is installed at the top of the selection lever at a position between the up- and down-shift switches, and turns on or off the up- or down-shift switch. A projection guide plate, having an inclined surface at one end thereof, is provided on the selection lever. The control device also has a rotary plate return means for giving an elastic returning force to the rotary plate. In this control device, the actuated direction of the actuation buttons of the two shift switches is equal to that of the manipulation lever, thus accomplishing a desired operational reliability of the 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. |
