A push-button or button is a simple switch mechanism to control some aspect of a machine or a process. Buttons are made out of hard material plastic or metal; the surface is flat or shaped to accommodate the human finger or hand, so as to be depressed or pushed. Buttons are most biased switches, although many un-biased buttons still require a spring to return to their un-pushed state. Terms for the "pushing" of a button include pressing, mashing, slapping and punching; the "push-button" has been utilized in calculators, push-button telephones, kitchen appliances, various other mechanical and electronic devices and commercial. In industrial and commercial applications, push buttons can be connected together by a mechanical linkage so that the act of pushing one button causes the other button to be released. In this way, a stop button can "force" a start button to be released; this method of linkage is used in simple manual operations in which the machine or process has no electrical circuits for control.

Red pushbuttons can have large heads for easy operation and to facilitate the stopping of a machine. These pushbuttons are called emergency stop buttons and for increased safety are mandated by the electrical code in many jurisdictions; this large mushroom shape can be found in buttons for use with operators who need to wear gloves for their work and could not actuate a regular flush-mounted push button. As an aid for operators and users in industrial or commercial applications, a pilot light is added to draw the attention of the user and to provide feedback if the button is pushed; this light is included into the center of the pushbutton and a lens replaces the pushbutton hard center disk. The source of the energy to illuminate the light is not directly tied to the contacts on the back of the pushbutton but to the action the pushbutton controls. In this way a start button when pushed will cause the process or machine operation to be started and a secondary contact designed into the operation or process will close to turn on the pilot light and signify the action of pushing the button caused the resultant process or action to start.

To avoid an operator from pushing the wrong button in error, pushbuttons are color-coded to associate them with their function. Used colors are red for stopping the machine or process and green for starting the machine or process. In popular culture, the phrase "the button" refers to a button that a military or government leader could press to launch nuclear weapons. Akin to fire alarm switches, some big red buttons, when deployed with suitable visual and audible warnings such as flashing lights and sirens for extreme exigent emergencies, are known as "scram switches"; such buttons are connected to large scale functions, beyond a regular fire alarm, such as automated shutdown procedures, complete facility power cut, fire suppression like halon release, etc. A variant of this is the scramble switch which triggers an alarm to activate emergent personnel to proactively attend to and go to such disasters. An air raid siren at an air base initiates such action, where the fighter pilots are alerted and "scrambled" to their planes to defend the base.

The J. Dupuy Stone House is located on Krum Road near Kerhonkson, New York, United States, in the Ulster County town of Rochester, it was modified later. On the property are several other outbuildings, including a stand-alone smokehouse, they and the house were listed on National Register of Historic Places in 1997. The 2.5-acre lot with the house and outbuildings is located on the south side of Krum Road half a mile east of its eastern end at Queens Highway. The house is surrounded by mature spruce and maple trees, the only such growth in a large area of open fields; the terrain is level, providing views of the Catskill foothills to the west and the Shawangunk Ridge to the east. The house itself is a five-bay one-and-a-half-story stone building with clapboard siding on the upper half-story, it is topped with a standing-seam metal gabled roof pierced by brick chimneys at either end. On the south side is a two-bay, two-story clapboard-sided wing added later. Fenestration is regular. All first-story windows are modern vinyl replacements for the originals.

Those on the first story have louvered wooden shutters. Those on the upper story of the north facade skip bays. A small wooden deck is located in front of the main entrance, running the width of the house. A stone walk leads from the front door to the road. On the east of the driveway there is a rectangular one-story frame clapboard-sided shed with corrugated metal gable roof and a one-story shed-roofed addition, it has a board-and-batten strap-hinged door on the east. Behind it and the house, to the southeast, is the smokehouse, a single-story front-gabled rubblestone building with a plank front door; the house was built around 1840 in the classic linear form of many stone houses of that era. The smokehouse is one of only six extant in the town of Rochester. In the early 20th century the front was raised to a full story, the only stone house in town where this was done. In the years of that century, the hip roofed front porch was removed. There have been no other major alterations to the house.
