Mechanical structure.
The travel switch is a switch used to control the position of mechanical movement, usually composed of contacts, springs, rollers, levers, etc., and its mechanical structure varies according to different applications and needs, but generally includes the following parts:
1.Contacts: Used to connect or disconnect circuits, switching circuits according to the position of moving objects.
2.Spring: Used to provide power for the contact to return.
3.Roller: In contact with the surface of the moving object, when the moving object moves to a certain position, the roller will drive the lever or other mechanism to trigger the contact.
4.Lever: When the roller moves to a certain position, the lever is subjected to a force that triggers the contacts.
How it works. The working principle of the travel switch is to switch the circuit according to the position of the moving object. When the moving object moves to a certain position, the roller will drive the lever or other mechanism to trigger the contact, thus switching the state of the circuit. Typically, a travel switch has only two states: on and off.
Structural features. The structural characteristics of the travel switch mainly include the following aspects.
1.Simple structure: The mechanical structure of the travel switch is relatively simple, mainly composed of contacts, springs, rollers, levers, etc., which is easy to manufacture and maintain.
2.Easy to operate: The operation of the travel switch usually only needs to be triggered by moving the moving object, and does not require complex operation steps.
3.Adaptable: The travel switch can be adapted to different applications and needs, such as controlling the opening and closing of doors, controlling the movement of robotic arms, etc.
4.Safe and reliable: The travel switch has high safety and reliability, and can work stably in different environments.
