la42按鈕(niu)開關該如何接線?

控(kong)(kong)制(zhi)(zhi)三相或單相電機均可，但不能直接(jie)(jie)控(kong)(kong)制(zhi)(zhi)，只能通(tong)過(guo)交流接(jie)(jie)觸器控(kong)(kong)制(zhi)(zhi)，按鈕(niu)LA42哪家(jia)好，又(you)因為該組合按鈕(niu)開關沒有停止鍵，一般只作為電機順、逆(ni)轉點動控(kong)(kong)制(zhi)(zhi)的。

 三個按鈕中。SB1是停止按鈕，SB2和SB3是正轉和反(fan)轉啟動按鈕。  因為(wei)SB2和SB3用常閉觸點進行(xing)了互(hu)鎖，所以(yi)可以(yi)進行(xing)急反(fan)車(che)操作.
