Schneider Electric Knob Selector Switch SPDT 22 mm Cutout Diameter Illuminated 3 Positions XB4BK135B5

Schneider Electric model XB4BK135B5 is a premium knob selector switch from the Harmony XB4 series, designed for precise industrial control applications. The illuminated selector switch features a compact 22 mm cutout diameter, making it ideal for installations with restricted space while providing enhanced visual feedback with its illumination.

This selector switch offers three positions and a SPDT (Single Pole Double Throw) contact configuration, ensuring versatile switching capabilities. It incorporates a robust knob actuator that operates with a 45° angle of throw, facilitating accurate and reliable switching operations.

Constructed with tough chromium-plated metal, the switch displays a smooth silver finish that is highly resistant to corrosion. Utilization of silver alloy contacts minimizes contact resistance, promoting efficient electrical conductivity and longevity under repeated use.

Designed and tested for demanding industrial environments, it boasts superior ingress protection with IP67 and IP69 ratings, making it resistant against dust and ingress of water at high pressure. Additionally, the switch complies with UL and CSA safety standards, and features mechanical protection rated IK06 alongside shock resistance per IEC 60068-2-27.

It is supplied with contact blocks and can be mounted inside suitable enclosures as part of larger control panel assemblies.

Typical applications include operation of dangerous motors requiring secure human control and public infrastructure such as lighting control in restrooms and corridors. Its secure design ensures only authorized personnel can operate the switch, preventing accidental activations.

The knob actuator provides precise control in a compact 22 mm mounting diameter. Illuminated design enhances visibility and operational status indication. Equipped with screw terminals for reliable electrical connections.

Robust IP67 and IP69 ingress protection ratings ensure durability in harsh industrial environments. The switch operates with a 45° angle of throw for accurate switching actions. Constructed with silver alloy contacts to reduce contact resistance and improve longevity.

Certified to UL and CSA standards, guaranteeing safety and performance. Mechanical protection rating IK06 and shock resistance certified to IEC 60068-2-27 standards. Suitable for industrial control, public building lighting, and motor operation requiring secure human intervention.
