A push button is a simple yet essential electrical component used to control the operation of machines, systems, and devices. It functions by momentarily completing or breaking an electrical circuit when pressed, allowing for the activation or deactivation of a particular process. Push buttons are commonly found in control panels, machinery, and consumer electronics, providing a straightforward interface for users to interact with equipment. Available in various designs, including illuminated, momentary, and toggle versions, push buttons offer flexibility and ease of use for controlling different types of electrical devices.
