The limit switch is an electrical equipment switch used to limit the limit position of the fitness exercise of the industrial equipment. The switch has contacts and non-contact. Capacitor grid relativity visualization. Install the travel switch on the movable member of the equipment, and install the limit position block or the reverse installation position on the support point of the relative speed. When the contact point of the mechanical equipment of the travel switch touches the stopper, the control circuit is disconnected (or changed), and the mechanical equipment stops running or changes the operation. Due to the inertial force of the mechanical equipment, the travel switch has a certain over-travel arrangement to protect the switch from being damaged. There are many non-contact methods, including reed switches, optics, induction, etc.
Limit switches, also known as travel switches, can be installed on objects with relatively static data (such as fixed structures, door covers, etc., commonly known as still life sketches) or moving objects (such as safe driving, doors, etc., commonly known as animals) superior. When the animal is close to the still life sketch, the crankshaft of the switch pushes the connection function of the switch, causing the closing connection function to break or the disconnection point to close. Control circuit and motor.
Limit switch is a common small current command household appliance. Use the impact of manufacturing molecular thermal motion components to complete the connection of the touch posture or disconnect the control circuit to achieve a certain adjustment location. Usually, such switches are used to define the position or schedule of molecular thermal motion, so that the exercise machine can be automatically terminated, reciprocating, variable speed, or fully automatic back and forth exercise. In the automatic control system, the function of the limit switch is to complete the sequence program, precise positioning manipulation and position condition inspection. It is used for scheduling and positioning maintenance of industrial equipment. Construction: Consists of the actual operating head, the contact point system software and the casing. In real manufacturing, limit switches are installed in prearranged positions. When the control module installed on the manufactured molecular thermal motion component collides with the travel switch, the contact point posture of the limit switch completes the conversion of the power circuit. Therefore, the travel switch is a household appliance that switches the power circuit according to the travel arrangement position of the fitness movement component. Its functional principle is similar to that of buttons, and it is widely used in various CNC lathes and lifting equipment. In the control circuit of the elevator car, the travel switch is also used to control the speed of opening and closing the door, the limit of the automatic opening and closing of the door, the maintenance of the lowest value of the vehicle, and the limit switch can be installed in objects with relatively static data (such as fixed architecture, door covers, etc., called still life sketches) or moving objects (such as safe driving, doors, etc., called animals). When the animal is close to the still life sketch, the crankshaft of the switch pushes the connector of the switch causing the closing connector to break or the disconnecting connector to close and close. Control the pose of circuits and structures.
