Functions of the buttons


 Buttons serve to fasten and close and in some cases to decorate the shirt or coat, buttons are also present in TV remote controls so that you turn the TV on and off or you change channels, to raise and lower the volume ... Although we do not realize it. We use buttons very often, as for example when you play the game the control is made up of buttons, in an elevator we also press buttons, when we play an instrument, such as the clarinet, we are playing several buttons.

Our fingers press  many buttons every day although we  do not realize it.
The buttons have 2 functions:

- They serve to fasten and close almost all garments, and in some cases ornaments.
-In electrical devices if we press them ,they can perform various functions.
