6. In the electric circuit of current 5A~6A, as the stroke of controlling the motion mechanism or changing the direction or speed of its movement
 One type of travel switch, position switch (also known as limit switch), is a commonly used small current main electric appliance. The collision or control circuit is realized by the collision of the moving parts of the production machinery to make the contact action to achieve a certain control purpose. Typically, such switches are used to limit the position or travel of the mechanical motion, allowing the motion machine to automatically stop, reverse, shift, or automatically reciprocate at a certain position or stroke.
 In an electrical control system, the position switch functions to achieve sequential control, position control, and position status detection. Used to control the travel and limit protection of mechanical equipment.
Construction: consists of the operating head, the contact system and the housing.
 In actual production, the travel switch is installed in a pre-arranged position. When the module mounted on the moving part of the production machine hits the travel switch, the contact of the travel switch acts to realize the switching of the circuit. Therefore, the stroke switch is an electric appliance that switches the circuit according to the stroke position of the moving part, and its function is similar to that of the button.
 The travel switch is widely used in all kinds of machine tools and lifting machinery to control its stroke and limit the terminal. In the control circuit of the elevator, the travel switch is also used to control the speed of the switch car door, the limit of the automatic door opening and closing, and the upper and lower limit protection of the car.
 The travel switch can be mounted on a relatively stationary object (such as a fixed frame, a door frame, etc., referred to as a still life) or a moving object (such as a car, a door, etc., referred to as an animal). When the animal approaches the still life, the contact of the switch's linkage drive switch causes the closed contact to break or the open contact to close. The operation of the circuit and mechanism is controlled by the change of the opening and closing state of the switch contacts.
