Tactile switches – These are miniature-sized switches primarily used to mount on the PCBs.You use this type of switch when you have to break a circuit connection momentarily. Push to break switch – When you press these types of witches, they will break a connection.Widely used to reset a microcontroller, doorbells, turn the light momentarily on, etc. The button brings two pins in contact when you press. Push to make switch – This is the most commonly used type of switch.I have listed the most common push buttons below. There are several types of switches you will come across. The top and bottom rows are shorted internally, as shown in the image. Pushbuttons come in various sizes and colors.Īs you can see, either you can use the left side or the right side of the switch for the operation. Closed State – When you are pushing the button.Open State – When you are not pressing the push button.This mechanism allows the button to return to the previous state once you stop pressing them. Push buttons contain a spring mechanism inside. You can use the pushbuttons easily with Arduino. Push-button, also known as a momentary switch, makes or breaks a connection. Through-hole style helps you to connect them on the breadboard easily. Quick Tip: Buy the push button switches, which come in through-hole PCB style.
