The Kontakt-Simon TW7L.01/149 is a high-quality intermediate switch module engineered for advanced lighting control systems. This device allows for the operation of a single light source from three or more different locations, making it an essential component for hallways, staircases, and large rooms. The unit features an integrated LED backlight with a clearly visible staircase pictogram, ensuring the switch is easy to locate in low-light conditions. Finished in a sophisticated matte black, this switch integrates seamlessly into modern interior designs while providing reliable electrical performance.

Advantages

The primary benefit of this intermediate switch is its ability to facilitate multi-point lighting control, which significantly enhances convenience in residential and commercial spaces. The inclusion of an LED backlight with a dedicated staircase symbol provides both functional utility and aesthetic appeal, helping users identify the switch in the dark. The quick-connection terminal system ensures a secure and efficient installation process, reducing labor time for electricians and DIY enthusiasts alike. Furthermore, the robust construction and 10 AX rating ensure long-term durability and safety for standard lighting circuits.

Suitable for

• Controlling lighting from three or more locations
• Residential hallways and long corridors
• Staircase lighting systems
• Commercial office spaces requiring multi-point switching

This switch may not be suitable for high-power appliance control or circuits exceeding the 10 AX rating. It is specifically designed for intermediate switching configurations and will not function correctly if used as a standard single-pole or two-way switch without the appropriate wiring setup.

Key specifications

• Rated current: 10 AX
• Rated voltage: 250 V
• Connection type: Quick connection terminals
• Backlight: Integrated LED with staircase symbol
• Color: Matte black
• Function: Intermediate switch

To install the Kontakt-Simon TW7L.01/149, ensure the power supply is disconnected at the main circuit breaker. Strip the wires to the required length and insert them into the quick-connection terminals until they are firmly locked in place. The module should be mounted into a standard electrical wall box. Once secured, attach the appropriate frame and cover plate to complete the installation. Always verify the wiring diagram for intermediate switching to ensure all connections are correct before restoring power.

What to consider before purchase

• Verify that your current wiring supports intermediate switching (requires four-wire configuration)
• Ensure the switch is compatible with your existing frame series
• Check that the load does not exceed the 10 AX rating

For optimal performance and safety, it is recommended to have this switch installed by a qualified electrician, especially when integrating it into complex multi-point lighting circuits.
