Abstract (en)
A switching device has an operation member (19) having an operation key (17) which is connected to and rotatably supported by a key holder lever (18); a driving lever (20) engaged with the operation member (19) and rotationally driven when the operation key (17) is pressed; and a switching element (21) press-driven by the rotationally-driven driving lever (20), the operation key (17) with a keyboard operational configuration disposed at a front surface of a front panel (11) being pressed downward. Here, a switching element (21) is mounted on a circuit substrate (14) which is held upright, and a spacing d between the circuit (14) and the driving lever (20) is set to a value smaller than a radius r of a boss (13c) serving as rotation axis of the driving lever (20), thereby preventing the driving lever (20) from being disconnected even when a simple attachment structure is employed. <IMAGE>
