Pushbutton Switches
Pushbutton switches are electrical actuators composed of buttons that, when pushed, either close or open the electrical circuits to which they are connected. They can be used to control a wide variety of electronic devices.

Each pushbutton variety is applied in a wide variety of contexts, such as in computers, at crosswalks, telephones, industrial machinery, security systems, ATMs, military equipment, casino gaming (slot machines), fitness equipment and a wide variety of other devices.
Pushbutton switches are among the most simple electric switch varieties. They are similar to toggle switches, in that they are usually used to perform simple circuit modifications. Both toggle switches and pushbutton switches are intuitive and easy to use. Operating a pushbutton switch involves simply depressing the switch until it performs its desired action. They are often equipped with tactile enhancements that help indicate to their users whether or not they have completed their intended action. Pushbutton switches may be recessed, flush, or raised. Recessed buttons are below the base of a product; this prevents accidental switching. Flush switches, on the other hand, are flush with the outside of a surface. Raised buttons are above the level of a surface and are simple to find and push.
Pushbutton switches, like all other electrical switch varieties, are used to change the configuration of the electrical circuits to which they are connected. When an electrical circuit is open, electricity cannot flow through it continuously, thus preventing the operation of the electric device of which the circuit is a part. When a pushbutton switch is used to close an electric circuit, electricity can flow through the circuit uninhibited, thus allowing for the operation of the device of which the circuit is a part. Pushbutton switches can allow for the sustained or momentary closure of a circuit, depending on their construction. In many cases, such as in computer keyboards or in other similar interface equipment, pushbuttons are fitted with springs that make the switch retract when it is not depressed, thus keeping the circuit open. Such momentary closure of a circuit can allow for the brief transmission of electricity from one place to another. In other cases, push buttons can allow for continued electrical flow; such switches have 鈥渙n鈥 and 鈥渙ff鈥 positions, which are engaged or disengaged with each push of the switch. Whatever their use, pushbuttons are valuable tools wherever they are installed.
