Explanation Push Button and symbols

        First we will play with the pushbutton (tactile) or the push button on. When this button is pressed, then the path will be closed (ON), when released the line will re-open (OFF). Buttons are widely used for equipment such as remote, keypad, keyboard, or buttons for setting TV, ld or the like.

Pushbutton and symbols

        Above picture is a form of physical pushbutton and one of the symbols pushbotton for NO (Normally Open) in electronic circuits. Based on these symbols, Normally Open means that the normal condition (before it is pressed), then the terminal in a state not connected (open, open). But when pressed, each terminal will be connected.

        In addition to the type of NO, there is also pushbutton type NC (Normally Close), meaning that when the normal condition (before it is pressed), foot terminal in a state terturup / connected (Close), but when pressed, foot terminal is open (not connected). In this ebook, we will use this type of pushbutton NO.

 

        LED with a pushbutton switch. If the button is pressed, the LED will light up, if released, LED back extinguished. To perform this experiment, prepare a pushbutton, an LED, and a resistor. Prepare some jumper cables to assemble these components.

For His experiments I will post in the next post
