Introduction
Push buttons have been in the field of electronics for a long time. It was invented in the early 18th Century and had no great purpose rather than being on the radio. The radio had a push button that would take you to the saved radio stations. The push button then has made history with a lot of advancements. A variation of it is present on your phone lock and its present in many other devices.
Modern devices that have remote control also have push buttons
Push Button
Push button switches come in a variety of shapes and sizes, and they can be categorized into two main types: momentary and latching switches.
Momentary switches are designed to return to their original position when the button is released. They are typically used to control temporary functions, such as turning on a light or activating an alarm. Latching switches, on the other hand, are designed to remain in the position that they are pushed until they are pushed again. These switches are often used to control permanent functions, such as locking a door or turning on a motor.

How does a Push Button work in the Circuit?
Push Buttons switches are designed to return back to its original position when the button is released. These type of switches are also called as momentary switches. In this simple circuit, the Push button is used to trigger the LED ON when the pressure is applied. The Push button completes or closes the circuit and allows the flow of current. This process turns ON the LED , while the button is pressed. The moment the button is released the LED will turn OFF. In the coming activities we will learn more applications of the Push Button.

Conclusion
The Push button have very useful applications like launching a nuclear weapon to the toys. Starting of with the most simplest circuit sets the basic for the next parts of the activities. The simple circuit that uses the push button will always remain identical to the one performed in the activity today.
