Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following Londonfl jerseys supplyn Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of swomen nfl jerseystaying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yecheap nfl jerseys wholesales," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

        產品介紹
        行程開關又稱限位開關,是一種常用的小電流主令電器。利用生產機械運動部件的碰撞使其觸頭動作來實現接通或分斷控制電路,達到一定的控制目的。通常,這類開關被用來限制機械運動的位置或行程,使運動機械按一定位置或行程自動停止、反向運動、變速運動或自動往返運動等。 

            在電氣控制系統中,位置開關的作用是實現順序控制、定位控制和位置狀態(tài)的檢測。用于控制機械設備的行程及限位保護。構造:由操作頭、觸點系統和外殼組成。

            在實際生產中,將行程開關安裝在預先安排的位置,當裝于生產機械運動部件上的模塊撞擊行程開關時,行程開關的觸點動作,實現電路的切換。因此,行程開關是一種根據運動部件的行程位置而切換電路的電器,它的作用原理與按鈕類似。

            行程開關廣泛用于各類機床和起重機械,用以控制其行程、進行終端限位保護。在電梯的控制電路中,還利用行程開關來控制開關轎門的速度、自動開關門的限位,轎廂的上、下限位保護。

            行程開關可以安裝在相對靜止的物體(如固定架、門框等,簡稱靜物)上或者運動的物體(如行車、門等,簡稱動物)上。當動物接近靜物時,開關的連桿驅動開關的接點引起閉合的接點分斷或者斷開的接點閉合。由開關接點開、合狀態(tài)的改變去控制電路和機構的動作。適用于交流50Hz。電壓至380V電流至3A的控制電路中,作控制機床工作行程之用。
