FAQs

What does '2NO' mean for this switch?

'2NO' signifies that the switch has two sets of contacts that are normally open. These contacts will close (complete a circuit) when the switch is actuated into a specific position.

What is the IP rating of this switch?

The switch has an IP67K rating, indicating high protection against dust ingress and immersion in water up to 1 meter, with added protection against high-pressure water jets.

Can this switch be used outdoors?

With its IP67K rating, the switch is suitable for many outdoor applications where it may be exposed to dust and water. However, prolonged direct exposure to harsh weather conditions should be considered for overall system design.

What size panel cutout is required?

A standard 22.3mm diameter hole is required for mounting this selector switch.

Can I use this switch with AC or DC power?

This switch is a mechanical actuator; its compatibility with AC or DC power depends on the electrical ratings (voltage and current) of the circuits it is controlling. Always check the switch's specifications against your circuit requirements.

Does this switch require a separate illumination module?

The product description mentions 'Suitable for illumination', implying that an illumination module might be available or compatible, but it is not inherently included with this specific toggle switch unit.

What is the warranty period for this Siemens switch?

Warranty information is typically provided by the retailer or distributor. Please refer to your purchase documentation for specific warranty details.

Troubleshooting

Switch does not change circuit state

Verify that the switch is securely mounted and that the toggle action is not obstructed. Check wiring connections to ensure they are correct and firmly attached to the terminals. Confirm the control voltage is applied and correct for the circuit.

One or both NO contacts do not close

Inspect the internal contacts for dirt or debris; clean gently if necessary. Ensure the switch is being moved to the correct position. If the issue persists, the switch may be faulty and require replacement.

Switch feels loose or wobbly

Tighten the mounting nut securing the switch to the panel. Ensure the panel material is rigid enough to support the switch.

Pros and Cons

Pros

  • Robust construction for industrial environments.
  • High IP rating (IP67K) ensures durability against dust and water.
  • Clear 3-position control for versatile operation.
  • Reliable performance expected from Siemens products.
  • Easy integration into standard 22.3mm panel cutouts.

Cons

  • Requires a specific panel cutout (22.3mm hole diameter).
  • Only provides normally open contacts; no normally closed functionality.
  • Front ring is plastic, which may be less durable than metal in extreme conditions.
  • Setup may require basic electrical wiring knowledge.

Setup, Compatibility & Care

Setup:

This switch requires a standard 22.3mm diameter hole for mounting in a control panel. Ensure the panel thickness is within the compatible range for the threaded mounting mechanism. Connect wires to the terminal block according to the desired circuit configuration, noting that the two contacts are normally open (NO).

Compatibility:

The switch is designed for use within electrical control systems. It is compatible with other components in the Siemens SIRIUS ACT series. Ensure your control voltage and current ratings are within the switch's specifications to prevent damage.

Care:

Regularly inspect the switch for any signs of physical damage. Clean the exterior with a slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners, as they can damage the plastic components. Ensure connections remain tight and free from corrosion.
