A valve position switch is a commonly used low-current control device. The movement of the mechanical components in the production machinery is utilized to cause their contacts to move, thereby enabling the connection or disconnection of control circuits to achieve certain control objectives. Typically, such switches are used to limit the position or stroke of mechanical motion, enabling the moving machinery to stop automatically at a certain position or stroke, move in the reverse direction, change its speed, or move back and forth automatically. In electrical control systems, the valve position switch serves to enable sequential control, position control, and detection of the position status. Used to control the travel of mechanical equipment and provide valve position protection. Structure: It consists of an operating head, a contact system, and a housing.
