How to use

Switch inserts must be installed by a qualified electrician in accordance with local regulations. Before installation, disconnect power and verify absence of voltage. Connect the phase and neutral conductors to the designated terminals, ensuring rigid wires are properly inserted into the screwless clamps up to 2.5 mm diameter. Fit the mechanism into the matching frame or cover plate variant; if using a model without claws, secure according to the frame manufacturer’s instructions. After wiring and mounting, restore power and verify correct switching operation and glow lamp indication.

Replace the integrated glow lamp with specified LED replacement types for lower power consumption and longer life. For safety and warranty compliance, installation and any lamp replacement should be performed by a qualified professional and in accordance with national electrical standards.
