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

Abstract: 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.

Description: THE BUTTON PROVIDING THE ILLUMINATION OF THE MACHINE SECONDARY FUNCTIONS FROM A SINGLE LIGHT SOURCE The present invention relates to the illumination of more than one function buttons on the household appliances control panel, from a single light source. In the prior art, when each secondary function button is pushed, each of them has to be directly connected to a light source in order that the pushed button can fulfill its function. The buttons are generally illuminated from individual light sources and in order to provide this, such electrical equipment as cables, relays etc. are required to be used. The object of the present invention is to realize the illumination of the secondary function buttons in household appliances, by using a single light source. In order to achieve the object of the present invention, the embodiment of the button, illuminated from a single light source is shown in the attached drawings, wherein: Figure 1 is the view of the button at pushed (on) position Figure 2 is the view of the button at neutral (off) position The parts shown in the drawings are separately numerated as follows: (1) Light source (2) Panel (3) Translucent portion of the button (4) Light-proof portion of the button (5) Light-proof portion claws The secondary function buttons of the present invention consist of two structural materials, namely translucent (3) and light proof materials. The portion facing the lower part of the 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 at the normal (off) position, the light-proof portion (4) extends towards the back side of the translucent portion (3), inside the panel. Claws (5) are provided on the part of the light proof portion (4) which stays inside the machine with regard to the level of the panel. Whereas, the proximate end part of the translucent portion (3) to the machine is configurated in line with the shape of the light-proof portion (4) in such a manner that a part of it enters the said light-proof portion. When the button is at normal (off) position, the claws (5) pass from the back of the button space of the panel (2) to provide the light-proof effect. When the button is brought to "on" position by being pushed, a part of the translucent portion of the button enters the lower panel level and the light coming from the single light source (1) inside the panel, is transmitted through the translucent portion to provide the illumination of the button. When the button is pushed again, the translucent portion comes out of the panel (2) level and the light transmission is blocked by the light-proof portion (4) of the button.

Claims: CLAIMS 1. A button providing the illumination of secondary function buttons of a machine, from a single light source characterized in that; the portion of the secondary function buttons which are formed by two materials, namely translucent (3) and light proof (4) parts, 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 and that 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 light from the only light source (1) inside the panel to be transmitted in order to provide the illumination of the button and 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. 2. A button providing the illumination of secondary function buttons of a machine from a single light source according to claim 1 , characterized in that the portion of the secondary function buttons facing the lower part of the panel level is made of light-proof (4) material. 3. A button providing the illumination of secondary function buttons of a machine from a single light source according to claim 1 , characterized in that the portion of the secondary function buttons facing the upper part of the panel level is made of translucent (3) material. 4. A button providing the illumination of secondary function buttons of a machine from a single light source according to Claims 1 to 3, characterized in that when the button is at the normal (off) position, the light-proof portion (4) extends towards the back side of the translucent portion (3), inside the panel, whereas, the proximate end part of the translucent portion (3) to the machine is configurated in line with the shape of the light-proof portion (4) in such a manner that a part of it enters the said light-proof portion. 5. A button providing the illumination of secondary function buttons of a machine from a single light source according to claims 1 to 4, characaterized in that claws (5) are provided on the part of the light proof portion (4) which stays inside the machine with regard to the level of the panel and when the button is at normal (off) position, the claws (5) pass from the back of the button space of the panel (2) to provide the light proof effect. 6. A button providing the illumination of secondary function buttons of a machine from a single light source according to Claims 1-5, characterized in that the single light source (4) is positioned below the panel (2), inside the machine at a height to be able to see all buttons depending upon the level of the button.
