6. In electrical circuits with current 5A ~ 6A, it is used to control the travel of the motion mechanism or change its motion direction or speed

Travel switch, a position switch (also known as a limit switch), is a commonly used low current main order electrical.The contact action of the production machinery moving parts is used to realize the switching on or breaking of the control circuit.In general, such switches are used to restrict the position or stroke of mechanical motion, to make the motor stop automatically, reverse motion, variable speed motion or automatic round-trip motion by a certain position or stroke. 

In electrical control system, position switch is used to realize sequence control, position control and position state detection.Used to control the travel and limit protection of mechanical equipment.

Construction: consists of operating head, contact system and shell. 

In the actual production, the travel switch is installed in the prearranged position. When the module installed on the production machinery moving parts bumps the travel switch, the contact action of the travel switch can be realized to switch the circuit.Therefore, the travel switch is an electrical device that switches the circuit according to the travel position of the moving parts. 

Travel switch is widely used in various machine tools and lifting machinery to control their travel and carry out terminal limit protection.In the control circuit of the elevator, the travel switch is also used to control the speed of the door, the limit of the automatic opening and closing, and the protection of the upper and lower limit of the car. 

Travel switch can be installed on relatively static objects (such as fixed frame, door frame, etc., referred to as still life) or moving objects (such as vehicles, doors, etc., referred to as animals).When an animal approaches a still object, the contact at which the switch's connecting rod drives the switch causes a closed or closed contact.The action of the circuit and mechanism is controlled by the change of the switch contact.
