Push-button switches are simple electrical devices that control the flow of electricity in a circuit. When you press the button, it completes the circuit, allowing electricity to flow and powering connected devices. These switches can be found in various applications, from household appliances to industrial machinery, making them versatile and widely used. There are different types of push-button switches, including momentary and latching switches. Momentary switches only stay on while being pressed, while latching switches remain on after being pressed until they are pressed again. This functionality makes push-button switches essential for controlling lights, machines, and other electronic devices.
