The two-level deviation switch is mainly used to detect the deviation of the conveyor belt to prevent the deviation of the belt from causing material overflow and other failures. When the tape deviates, the edge of the tape drives the stick to rotate and squeeze the stick to tilt it. If the tilt of the stand rod is greater than the first-level action angle, the switch will send out a set of signals for warning, and if the tilt of the stand-up rod is greater than the second-level action angle, the switch will send another set of signals for shutdown. After the belt conveyor resumes normal operation, the stand roller is automatically reset.

There are two micro switches K1; K2 inside the two-stage deviation switch, which can be connected as normally open or normally closed according to actual needs.

1) The switch is installed on the fixed bracket of the rack in a balanced manner, and then welded to the tape rack;
2) The axis of the vertical stick is perpendicular to the side of the tape, and the distance between the vertical stick and the edge of the tape is 50mm-100mm;
3) The tape is located on the vertical stick At the bottom 1/3;
4) At least one pair of deflection switches must be installed every 50m of tape.
