Push Button: A Simple but Powerful Switch Mechanism
A push button is a simple switch mechanism that controls some aspect of a machine or a process. It is typically made out of hard material, such as plastic or metal, and has a flat or shaped surface that can be easily depressed or pushed by a human finger or hand. Push buttons are usually biased switches, which means they return to their original position after being pressed. Push buttons can either close or open an electrical circuit, depending on their design and function.

Push buttons are widely used in various devices and applications, such as calculators, telephones, kitchen appliances, doorbells, elevators, arcade games, industrial machinery, security systems, and more. Push buttons can also be color-coded or labeled to indicate their function or action. For example, red push buttons are often used for stopping or emergency situations, while green push buttons are often used for starting or activating something.
History of Push Button
The concept of push buttons in telephony originated around 1887 with a device called the micro-telephone push-button, but it was not an automatic dialing system as understood later. This use even predated the invention of the rotary dial by Almon Brown Strowger in 1891.
The first electric push buttons were patented in the 1880s and were used for various purposes, such as doorbells, telegraphs, alarms, and signals. One of the earliest examples of a push button switch was the Morse code key, which was used to send messages over long distances using electric pulses.
In the early 20th century, push buttons became more popular and widespread with the development of new technologies and industries, such as radio, aviation, automotive, and electrical engineering. Some of the key inventions and innovations related to push button technology include:
The first push-button telephone was introduced by Bell System in 1941, which used tones instead of pulses to dial numbers.
The first electronic calculator with a keyboard of ten numeric keys and four function keys was developed by Bell Punch Co. in 1961.
The first arcade video game with a joystick and a fire button was Computer Space by Nutting Associates in 1971.
The first personal computer with a graphical user interface and a mouse with one button was the Apple Macintosh in 1984.
Types of Push Button
Push button switches can be classified into two main types: momentary and latching. Momentary push buttons are switches that only close or open an electrical circuit when they are pressed. They return to their original state when they are released. Latching push buttons are switches that change their state with each press. They stay in their new state until they are pressed again.
Momentary push buttons are also known as normally open (NO) or normally closed (NC) switches, depending on whether they break or make an electrical circuit when they are pressed. NO switches are open when not pressed and closed when pressed. NC switches are closed when not pressed and open when pressed.
Latching push buttons are also known as on-off or toggle switches, depending on whether they have two or more positions. On-off switches have two positions: on and off. Toggle switches have more than two positions: on-on, on-off-on, etc.
Some examples of momentary and latching push buttons are:
