What is a limit switch? |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| A position switch—also known as a limit switch or end switch—is an electromechanical switch that responds to the mechanical movement or position of an object. As soon as a moving part, such as a workpiece, lever, or machine component, reaches a predefined position, it mechanically activates the switch. This opens or closes an electrical contact, which triggers a control signal or shuts down a machine. Position switches are used in industry for position monitoring, control, and safety of machines and systems. They are a central element in automation technology and are used wherever precise movements need to be detected and controlled. Thanks to their robust design, position switches are extremely reliable and durable. They operate independently of electromagnetic interference fields and offer a high degree of safety due to their galvanic isolation. Many models also have high protection classes (e.g., IP67) and can be used in harsh industrial environments. Typical applications can be found in: > Conveyor and packaging systems > Mechanical engineering and robotics > Lifting and gantry systems > Safety interlocks and end position controls Depending on the type of application, there are different designs and actuation types – such as lever, plunger, or spring bar switches. Modern position switches are compact, can be combined in many ways, and enable precise repeat accuracy down to the hundredth of a millimeter. |

Position switches from Telemecanique – precision and reliability for industrial applications |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Telemecanique position switches are known worldwide for their precise switching, high reliability, and maximum robustness. Their mechanical operation enables safe switching of loads, even under demanding industrial conditions. Thanks to their simple, proven functionality, they are used millions of times over – from automated production facilities to complex machine controls. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Reliable switching through mechanical precision A position switch operates by direct mechanical contact. As soon as a moving part—such as a machine slide or conveyor belt—reaches a defined position, the switch triggers a precise switching signal. Telemecanique position switches offer a switching point repeatability of up to 0.01 mm, ensuring precise control even after many years of use. Galvanic isolation makes them insensitive to electromagnetic interference—a decisive advantage in modern industrial environments. |

| Robustness and worldwide approvals Telemecanique position switches impress with their robust construction, high short-circuit resistance, and consistent performance even under extreme conditions. Thanks to international approvals (including CE, UL, CSA), they can be used worldwide – in almost all industrial sectors. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Maximum flexibility with the universal series The universal series from Telemecanique (XCM-D, XCK-D, XCK-P, and XCK-T series) offers maximum flexibility in planning and installation. Each actuator fits every series, and the heads can be rotated 360° in 15° increments. This saves time during selection and greatly simplifies installation. |
