Push Button

Push buttons are manually operated electromechanical switching devices used to start, stop, or control electrical circuits in industrial and domestic applications. They operate by momentary or maintained contact action to open or close a circuit when pressed. Common technical features include normally open (NO) or normally closed (NC) contacts, contact ratings suitable for control circuits, robust housings in plastic or metal, standard mounting sizes (such as 22 mm), and protection ratings for reliable use in control panels and machinery.
