THE BUTTON PROVIDING THE ILLUMINATION OF THE MACHINE SECONDARY FUNCTIONS FROM A SINGLE LIGHT SOURCE

摘要

The secondary function buttons are formed by two parts, namely translucent (3) and light-proof (4) parts. The portion facing the lower part of the continuous panel (2) level is made of light proof (4) material and the outer portion facing the upper part of the panel level when the buttons are at normal (off) position, is made of translucent (3) material. When the button is pushed to be brought to the pushed (on) position, a part of the translucent portion (3) of the button enters the lower part of the panel (2) level and provides the transmission of light from the only light source (1) inside the panel and thus illuminates the button. When the button is pushed again, the translucent part (3) inside the panel (2) is pushed-out and the light transmission is prevented by the light-proof portion (4) of the button.
