COMMON LIMIT SWITCH FAULTS

  • WORN INTERNAL CONTACTS

    Repeated mechanical operation can wear the switch contacts and produce intermittent or high-resistance signals.

  • MECHANICAL MISALIGNMENT

    The machine may no longer physically operate the switch correctly due to movement, wear, or adjustment.

  • DAMAGED ACTUATORS

    Roller arms, plungers, and levers can bend or break in harsh machine environments.

  • BROKEN CONTROL WIRING

    Vibration and repeated machine movement can damage conductors around limit switches.

  • PLC INPUT NOT CHANGING

    The switch may operate mechanically while the electrical signal fails to reach the controller.

  • MOISTURE OR DUST INGRESS

    Unsuitable or deteriorated enclosures can allow contamination to damage the switching mechanism.
