　　Travel switch, also known as position switch or limit switch, is a commonly used low current main control device. It utilizes the collision of moving parts in production machinery to move the contacts, thereby connecting or disconnecting the control circuit to achieve specific control objectives. Usually, this type of switch is used to limit the position or stroke of mechanical motion, causing the moving machinery to automatically stop, reverse, change speed, or automatically move back and forth at a certain position or stroke.

　　Travel switches play an important role in electrical control systems, mainly used to achieve sequential control, positioning control, position status detection, as well as control the travel of mechanical equipment and perform limit protection. It consists of an operating head, a contact system, and a housing, which may have different design features and functions depending on specific application scenarios and requirements.

　　When choosing a travel switch, some key factors need to be considered, such as current load, rated voltage, external dimensions, and wiring method. Excessive or insufficient load can cause damage to the travel switch, so it is necessary to choose the appropriate switch based on the actual load current. Rated voltage is also an important selection parameter that needs to be taken into consideration when making a choice. In addition, it is necessary to choose the appropriate external dimensions based on the actual installation scenario and installation hole size, as well as select the appropriate wiring method according to the actual situation.

　　There are various types of travel switches, which can be classified into multiple types based on their control methods and functions. For example, a single control switch is the most basic travel switch, with only one control button used to turn on or off circuits, usually used for controlling individual lamps or electrical equipment. The dual control switch can simultaneously control switches in two positions, making it convenient to control the same circuit in multiple positions. Relay switches can control the on/off of circuits through electromagnetic attraction and disconnection. When used in conjunction with wireless or smartphone devices, they can achieve remote control and timing switch functions. The touch switch adopts capacitive sensing technology, and the circuit can be turned on and off by simply touching the switch panel. It has the advantages of high sensitivity, fast response, and beautiful appearance.
