FAQs

What does IP66 and IP67 rating mean?

IP66 indicates protection against dust ingress and powerful water jets. IP67 indicates protection against dust ingress and immersion in water up to 1 meter for 30 minutes.

Can this switch be used for both AC and DC circuits?

Yes, the switch is rated for both AC (up to 240V) and DC (up to 250V) circuits, provided the maximum current of 10A is not exceeded.

What is the difference between NO and NC contacts?

NO (Normally Open) contacts are open when the switch is not actuated and close when actuated. NC (Normally Closed) contacts are closed when the switch is not actuated and open when actuated.

How many circuits can this switch control?

This is a Double Pole (DP) switch, meaning it can control two separate circuits simultaneously.

What is the purpose of the 'forced opening' feature?

The forced opening feature ensures that the Normally Closed (NC) contacts are physically forced open when the actuator is pressed, providing a reliable safety mechanism even if the contacts weld together.

What is the operating temperature range?

The switch is designed to operate reliably in temperatures ranging from -25°C to +70°C.

What type of terminals does the switch use?

The switch uses screw terminals for electrical connections.

Troubleshooting

Switch not triggering

Verify that the lever actuator is being fully depressed by the moving part. Check for obstructions around the actuator and ensure the switch is correctly aligned with the point of actuation. Confirm wiring is correct for the desired contact (NO or NC).

Intermittent operation

Inspect the lever for damage or wear. Check that mounting screws are tight and the switch housing is secure. Ensure electrical connections are clean and firmly made.

Short circuit or blown fuse

Double-check that the electrical load does not exceed the switch's maximum ratings (10A, 250V DC, 240V AC). Verify that wiring is correct and there are no stray wires or shorts. If using both poles, ensure they are wired independently and correctly.

NC contacts do not open

This indicates a potential failure of the forced opening mechanism. Discontinue use and replace the switch immediately, as this is a critical safety feature.

Pros and Cons

Pros

  • High level of protection against dust and water (IP66/IP67).
  • Durable construction suitable for industrial environments.
  • Versatile contact configuration (NO/NC) and double pole setup.
  • Safety feature with forced opening of contacts.
  • Wide operating temperature range for various conditions.

Cons

  • Plastic housing may be less resistant to impact than metal alternatives in extreme scenarios.
  • Lever actuator may require specific mounting orientation for optimal function.
  • Requires careful wiring to utilize both NO and NC contacts effectively.
  • Maximum current and voltage ratings must be adhered to for safe operation.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the switch in the desired location, ensuring the lever actuator can be reliably engaged by the moving part.
  2. Wiring: Connect the electrical terminals using appropriate gauge wire for the current and voltage. Ensure screws are tightened securely. The switch features screw terminals for easy connection. Refer to wiring diagrams for DP (Double Pole) configuration and NO/NC (Normally Open/Normally Closed) contact usage.

Compatibility:

  • This switch is designed for use in control circuits requiring position sensing.
  • Ensure the electrical load does not exceed the maximum ratings: 10A maximum current, 250V DC maximum voltage, and 240V AC maximum voltage.
  • The lever actuator should be compatible with the mechanical movement it needs to detect.

Care:

  • Keep the switch and its operating lever clean from debris that could impede its function.
  • Periodically inspect wiring connections for tightness and signs of wear.
  • While the IP rating provides excellent protection, avoid prolonged submersion beyond the specified limits.
  • Clean the exterior with a dry or slightly damp cloth; avoid using solvents.
