Because it is spring return, not stay-put\/latching, it does not serve as an emergency stop - a panel needing a fail-safe latching stop should specify a dedicated emergency-stop mushroom variant with a 1 NC contact instead.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54074905592091,"sku":"XB4BC21","price":12.97,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-xb4bc21-push-button-mushroom-black.jpg?v=1790852015","url":"https:\/\/stoklink.com\/products\/schneider-electric-xb4bc21-push-button-mushroom-black","provider":"Stoklink","version":"1.0","type":"link"}
