FAQ

Magnetic switch operates twice continuously:

  • Since the magnetic field of magnet is too strong or the sensitivity of magnetic switch is too high. Please contact to our RD department.

The LED flashes and turns off: Check whether the loading current is too high.

  • Yes:
    • a. Exchange magnetic switch with larger rated operating voltage, current, and contact rating.
    • b. Use relay or PLC to drive the load indirectly.
  • No: Please send back for examination.

The Malfunction of Magnetic Switch: Check wiring

  • Correct: Remove magnetic switch from cylinder, and use a magnet to test the switch.
    • Switch works: the magnetic field of the magnet inside the cylinder is not
      • enough or the sensitivity of magnetic switch is too weak.
      • Please contact our RD department.
    • Switch doesn’t work: Please send back for examination.
  • Wrong: Please correct it.

Contact point is unbreakable: Check whether the magnetic switch is overloaded.

  • No: Check the wire distance between the magnetic switch and the load is more than 10M or not.
    • Over 10M:Add an inductor (About 1000uH) to eliminate to capacitor impulse caused by long wiring.
    • Below 10M: Please send back for examination.
  • Yes:
    • a. Exchange magnetic switch with larger rated operating voltage, current, and contact rating.
    • b. Use relay or PLC to drive the load indirectly.

The LED on magnetic switch does not work: Check power supply type (AC or DC) of product

  • AC-powered product:
    • Switch works:LED is out of order. Please send back for examination.
    • Switch doesn’t work:Please refer《The Malfunction of Magnetic Switch》
  • DC-powered product:
    • Switch works:Check the polarity of wiring
      • Wrong:Please correct it.
      • Correct:Please send back for examination.
    • Switch doesn’t work:Please refer《The Malfunction of Magnetic Switch》
