Pushbutton Switches
Pushbutton switches use a push button as the actuator, or the moving part that applies force to the contacts. An LED may light pushbutton switches in order to indicate their position (on/off).
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. Most doorbells use this configuration. Raised buttons, used in crosswalks, are above the level of a surface and are simple to find and push.
Computers use a pushbutton switch as their power button. These switches are normally opened (N.O.) switches that, when pushed, close a circuit. After the circuit is closed, a message is sent to the motherboard, completing the shutdown process.
Pushbutton switches are used in a variety of settings, including in security systems, ATMs, military equipment, casino gaming (slot machines), fitness equipment, aerospace, agriculture, manufacturing, and construction equipment.
