See full text

A remote control apparatus has a plurality of manipulating buttons fitted in a plurality of windows, respectively, formed in a casing member, each of the manipulating buttons being formed of a transparent material and having a lower portion provided with a switch actuating projection and an upper portion disposed within each of the windows for allowing user to operate the button with his or her finger. A switch array includes a plurality of switches corresponding to the plural manipulating buttons and is mounted within the casing member such that each of the switches can be changed over between ON and OFF states by contact with a switch actuating projection in the operation of the corresponding manipulating button. A mode change-over switch is selectively movable to a plurality of positions for setting one of a plurality of predetermined modes in which the switch array is to be operated, and a display plate for displaying marks indicating functions of the individual manipulating buttons in the mode set by the mode change-over switch is movable with the mode change-over switch and is located between the button array and the switch array so that the marks can be visually recognized through the individual manipulating buttons, and so that the marks displayed correspond to the mode set by the mode change-over switch.
