Push Button Switches, also known as biased switches, are designed with a simple electric switch mechanism. They are used to control some aspect of a machine or a process. These switches are made out of plastic or other hard materials to deliver instant response at being pushed or pressed. They are generally used in control boards and panels in industrial and test equipment, computer mainframes and peripherals, process control, and medical instrumentation, among others.
