Troubleshooting

Switch does not operate when key is turned.

Verify power supply to the circuit. Ensure the key is fully inserted and turned to the correct position. Check internal wiring connections for the correct NO contact.

Key is difficult to turn or insert.

Inspect the keyhole for debris or obstructions. Ensure the switch is correctly mounted and not under mechanical stress from the panel. Do not force the key.

Switch fails after a short period of use.

Check for excessive current draw or voltage spikes in the connected circuit. Confirm the operating environment is within specified temperature limits. Inspect for physical damage.

Contacts do not make or break circuit as expected.

Re-verify wiring against the switch's contact configuration (1 NO). Test continuity of the NO contact with a multimeter when the switch is in different positions (power off).

Pros and Cons

Pros

  • Provides high security for controlling access to machinery or circuits.
  • Exceptional electrical and mechanical durability for long service life.
  • Robust build quality suitable for harsh industrial environments.
