　　Working principle of travel switch

　　Travel switch is a commonly used small current main control device, which uses the collision of production mechanical moving parts to make its contacts move to achieve the connection or disconnection of control circuits and achieve certain control objectives. Travel switches are divided into several types according to their structure, including direct action, roller type, micro action type, and combination type.

　　The function of stroke switch operation

　　Travel switch is a commonly used small current control device, whose main function is to achieve sequential control, positioning control, and position state detection. Specifically, the travel switch can be used to control the travel and limit protection of mechanical equipment. When the module installed on the moving parts of the production machinery collides with the travel switch, the contact of the travel switch will act, achieving circuit switching.

　　Travel switches can be installed on relatively stationary objects (such as fixed frames, door frames, etc., referred to as stationary objects) or moving objects (such as cranes, doors, etc., referred to as animals). In other words, it is an electrical device that can switch circuits based on the stroke position of moving parts, and its working principle is similar to a button.

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

　　Travel switch, also known as limit switch, is an electrical device that can switch circuits based on the travel position of moving parts. Its working principle is similar to that of a button switch, except that the travel switch requires external mechanical collision control. Specifically, when we saw the physical display, we opened the outer cover of the switch, which had a sealing gasket to prevent oil contamination from entering. Inside, we saw four contacts, one group normally open and one group normally closed. When the external machinery collides with the switch inside the rocker arm, the normally open point closes and the normally closed point opens. In practical work, the travel switch is installed in a pre arranged position. When the moving parts of the production machinery collide with the external actuator of the travel switch, the internal contacts of the travel switch act to achieve circuit switching.

　　Travel switches are widely used in various machine tools and lifting machinery to control their travel and provide terminal limit protection. In the control circuit of the elevator, a travel switch is also used to control the speed of opening and closing the car door, the limit of automatic door opening and closing, and the upper and lower limit protection of the car. Travel switches can be installed on relatively stationary objects (such as fixed frames, door frames, etc.) or moving objects (such as cranes, doors, etc.). When an animal approaches a stationary object, the connecting rod of the switch drives the contact of the switch to cause the closed contact to open or the open contact to close. Control the operation of circuits and mechanisms by changing the opening and closing status of switch contacts.
