The switch closes its contact only while pressed; it opens again when released.\u003c\/p\u003e \u003cp\u003eThe three-pin version enables various wiring configurations: two pins can be used as a changeover switch, or both switch contacts can be wired in parallel to distribute mechanical wear across multiple contacts. For digital inputs, simply querying the logic level is sufficient.\u003c\/p\u003e \u003cp\u003eThese push buttons are used in robotics projects for commands such as start and stop, on learning boards for input detection, in prototypes for user control, and in expansion modules as additional controls. Typically, a pull-up or pull-down resistor is activated on the microcontroller to filter out contact bounce.\u003c\/p\u003e \u003cp\u003eThe XH2.54 connector fits common modular systems and breadboards. For direct connections to larger connectors, an additional adapter cable simplifies wiring. With frequent actuation, wear resistance and contact reliability should be checked.\u003c\/p\u003e \u003ch3\u003eSafety notice\u003c\/h3\u003e \u003cp\u003eThe push button is intended exclusively for building prototypes and for testing and development purposes. Work on or near electrical installations is reserved for qualified electricians; consult a qualified electrician before commissioning it in circuits above 24 V or in safety-critical applications.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1* push button - with XH2.54 3P female connector\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65997801750877,"sku":"F23109061","price":2.61,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/taster-button-mit-xh254-3p-buchse-funduino-8761024.jpg?v=1791493880","url":"https:\/\/funduino.com\/en\/products\/push-button-with-xh2-54-3p-socket","provider":"Funduino","version":"1.0","type":"link"}
