A push button is classified as which type of device?

A push button is classified as a human interface device because it serves as a means for users to interact with electronic systems. This type of device allows individuals to send commands or control machinery through a simple physical action, such as pressing the button. Since push buttons translate human input into a signal that can be understood by a machine or controller, they are integral to creating intuitive user interfaces.

In the context of electrical systems, human interface devices like push buttons elevate the functionality of equipment by making it accessible and operable for users, thereby facilitating control over various processes or machinery directly.
