First Claim
1. A multi-function switch device for selecting and controlling any of a plurality of operational modes of a plurality of systems, the multi-function switch device comprising:
- a case body having a transparent display window fixed thereto and a plurality of clear keys movably attached to the case body, the clear keys being formed from a transparent material;
a mode selection switch arranged on the case body for allowing an operator to select any one of the operational modes of the systems;
a display unit accommodated in the case body so as to underlie the transparent display window and the clear keys, the display unit having a mode-display area defined therein to indicate the operational mode of the system selected by the mode selection switch through the transparent display window, and a plurality of operation-display areas defined to indicate various operative conditions of the system in accordance with the operational mode through the clear keys; and
a drive circuit accommodated in the case body to drive the display unit, the drive circuit being connected to the mode selection switch to thereby allow the display unit to display the operational mode and the operative conditions of the system selected.

Abstract
A multi-function switch device for systems includes a case body, a mode selection switch on the case body, a display unit and a drive circuit both accommodated in the case body. The case body is provided with a transparent display window and a plurality of clear keys made of transparent material. By manipulating the mode selection switch, and operator can designate any one of respective operational modes of the systems. The display unit is positioned under the transparent display window and the clear keys. In the display unit, there are defined a mode-display area for indicating the so-designated operational mode of the system through the transparent display window and a plurality of operation-display areas for indicating various operative conditions in the corresponding system through the clear keys, respectively.
