When described in more detail on the basis of the accompanying preferred embodiment the power button device according to the present invention.

3 to 6B show the power button device of the display device according to the present invention.

Therefore, the power button device of the present invention is basically provided with a power button 10 having a pressing portion 11 that can be pressed by hand.

In addition, a rear end of the pressing portion 11 of the power button 10 is provided with a rod-shaped operation rod portion 12, the light transmitting portion 13 is formed integrally on one side of the operation rod portion 12. It is configured to have.

In addition, the pressing portion 11 of the power button 10 and the operation rod portion 12 having the light transmitting portion 13 are separately provided for assembly to operate in the front and rear directions in the case 20. It is manufactured by injection molding.

Therefore, when the assembly is to be assembled to the case 20, the pressing portion 11 and the operation rod portion 12 of the power button 10 is assembled to be coupled to each other, wherein the button return means spring 14 is assembled to intervene. Therefore, when the pressing force of pressing the power button 10 by hand is removed, the spring 14 is always returned to its original position by the elasticity.

In addition, the rear end of the operation rod 12 of the power button 10 has a power switch 30 having a contact portion 31 which is pressed by the movement force moved in the front and rear direction of the operation rod 12 Is provided by the circuit board 32 constituting the circuit section.

On the one side of the power switch 30, an LED lamp 33 is provided on the circuit board 32 to provide light to the light transmitting unit 13.

In the above configuration, the power button 10 according to the present invention, that is, the pressing part 11 and the entire operation rod part 12 having the light transmitting part 13 is formed of a light emitting resin material through which light can be transmitted. do. At this time, since the surface of the pressing portion 11 is formed in an embossed state in which the surface of the common case 20 is in an uneven state, the pressing portion 11 surface is also configured to be embossed, thereby allowing a normal appearance form.

In addition, the power switch 30 allows a digital switch having good operability to be employed.
