Product Information

Full details

The Eaton 216518 is a robust, maintained selector switch designed for industrial control panels, offering reliable two-position operation. It's ideal for electricians and control system integrators needing a durable component for manual control applications. A key benefit is its IP66 rating, providing excellent protection against dust and water ingress. However, it requires a 22mm panel cutout and uses screw terminal connections, which might be less convenient for some installations.

FAQs

What does 'maintained' mean for this switch?

A 'maintained' switch means that once you move the actuator to a position (e.g., 'On'), it will stay in that position until you manually move it to another position (e.g., 'Off'). It does not return to a default position on its own.

What is the IP66 rating?

IP66 means the switch is protected against dust ingress ('6' - Dust-tight) and protected against strong jets of water ('6' - Water jets). This makes it suitable for many industrial and outdoor applications.

Can I use this switch for both high and low voltage circuits?

This switch is primarily designed for control circuits. Always verify the voltage and current ratings against your specific application requirements. Refer to the product datasheet for detailed electrical specifications.

How many circuits can this switch control?

This specific model has one normally open (N/O) contact. This means it can complete a circuit when activated. It is not designed for multiple independent circuits or changing between different sets of contacts simultaneously.

What is the size of the mounting hole required?

The Eaton 216518 requires a standard 22mm diameter mounting hole in the control panel.

Does this switch come with a bezel?

Yes, the Eaton 216518 comes complete with a titanium-colored front bezel as shown in the product description.

Can I change the actuator type or color?

This specific model features a fixed thumb-grip actuator and titanium bezel. For different actuator types (like key or toggle) or colors, you would need to look at other compatible Eaton RMQ-Titan components or series.

Troubleshooting

Switch does not change state

Ensure the actuator is fully engaged in the desired position. Check for any obstructions around the mechanism. Verify power is applied to the circuit controlling the switch if it's part of a larger system.

No continuity on the N/O contact

Verify that the switch is in the correct position to activate the N/O contact (typically 'Position I'). Ensure wiring to the N/O terminal is secure. Check if the switch has reached its end-of-life if used extensively.

Actuator feels loose or stiff

Inspect the switch mounting for proper tightening. Ensure no debris has entered the mechanism. If stiffness persists, consider replacing the unit, especially if operating temperatures are at the extremes.

IP rating compromised (visible dust/water ingress)

Immediately disconnect power. Inspect the seals around the bezel and the rear housing. Tighten the mounting mechanism. If damage is evident, replace the switch unit.

Pros and Cons

Pros

  • Durable construction suitable for harsh environments.
  • High level of protection against dust and water (IP66).
  • Ergonomic thumb-grip for easy operation.
  • Standard 22mm mounting for broad compatibility.
  • Reliable maintained switching function.

Cons

  • Limited to 2 positions and 1 N/O contact.
  • Screw terminals may require more time for installation compared to push-in types.
  • Does not include SmartWire-DT connectivity.
  • Bezel color is fixed at titanium.

Setup, Compatibility & Care

Setup:

  1. Ensure the control panel has a standard 22mm diameter mounting hole.
  2. Insert the switch actuator through the hole from the front of the panel.
  3. Secure the switch body to the panel using the provided mounting mechanism (typically a locking nut or ring).
  4. Connect the electrical load or control circuit to the screw terminals at the rear of the switch. Ensure power is disconnected before making connections.

Compatibility:

  • Panel Cutout: Requires a 22mm diameter hole.
  • Voltage/Current: Designed for control circuit applications; check specifications for maximum current (e.g., 6A) and voltage limits.
  • Contact Configuration: Suitable for circuits requiring one normally open (N/O) contact.

Care:

  • Cleaning: Wipe the exterior with a clean, dry or slightly damp cloth. Avoid using abrasive cleaners or solvents that could damage the plastic housing or bezel.
  • Environment: While IP66 rated, avoid prolonged direct exposure to extreme conditions beyond the specified operating temperature range (-25 to 70 °C).
  • Inspection: Periodically check screw terminal connections for tightness and inspect the actuator for any signs of damage.
