Abstract
A remote control device for remotely controlling an AV (audio visual) device includes an analog switch (30) formed of an operating element (31 or 41) and a pressure-sensitive resistor (35) which outputs a signal with various levels depending upon a pressing force applied to the operating element (31 or 41). By employing the analog switch (30 ) in a control button of the remote control device, it becomes possible to output a signal having various levels depending upon a pressing force applied to the control button (31 or 41). This allows a single control button to be used for a plurality of functions. Thus, it is possible to reduce the number of buttons, and a user can easily operate the remote control device in a simpler fashion.
