一級開關信號用于報警，如果將此信號與跑調整裝置相接，即可實現不停機狀態下的跑偏自動調整。 
二級開關信號用于停機，將此信號接至控制線路中，即可實現重度跑偏狀態下的自動停機。
當故障排除后，膠帶離開立輥正常運轉時，立輥可自動復位。 
為了適應戶外條件下長期使用，本產品均采用整體密封，內部金屬零件進行鍍鋅純化處理，外部零件除殼體外均做多層光亮鍍鉻，殼體為鑄鋁/不銹鋼制造，表面采用靜電噴涂技術處理，適宜在惡劣環境下使用。

適用范圍

雙向拉繩開關和兩級跑偏開關用于常規皮帶輸送機：地下、索道支撐皮帶輸送機：輪船裝卸系統；堆垛/取料輸送機；傾斜和梭式輸送機；起重機、挖掘機，起重臂限位：裙邊給料機/輸送機：重型極限開關檢測膠帶的跑偏量，是實現膠帶機控制的自動報警和停機的保護裝置。
