Generally, such switches are used to limit the position or stroke of the movement of the machine, so that the moving machine can automatically stop, move in reverse, shift or automatically move back and forth according to a certain position or stroke.
In the technical field of mold processing, at least two to three sliding blocks are generally needed to be matched with a movable mold and a fixed mold to realize the mold structure of a product. The movement strokes of the sliding blocks are different, and the movement sequence of the sliding blocks has strict regulations, otherwise, collision among all parts of the die can be caused, and the die is damaged or even scrapped. In order to confirm whether the action of the mold structure is completed or not and ensure that the actions of different mechanisms of the mold are performed according to a specified sequence, two travel switches are required to be arranged on each slide block, the forward movement and the backward movement of the slide block are respectively detected through the two travel switches, and the two travel switches corresponding to the forward movement signal and the backward movement signal on each slide block are a group of travel switches.
