How to use

Turn the button to switch the connected lighting circuit on or off. Installation should be performed by a qualified electrician in accordance with local electrical regulations: isolate the circuit power before connecting conductors, secure the switch into a compatible flush-mounted box, and attach the cover plate. Confirm correct polarity and tightness of terminal screws, then restore power and test operation.

Recommendations

For longevity, avoid exposure to direct water or continuous high humidity. Use the switch within typical household or commercial voltage and load ratings, and replace the unit if the actuator becomes stiff or contacts show signs of wear. For installations in damp or outdoor-adjacent locations, choose a product with appropriate ingress protection.
