How to use

Install the switch into a standard flush-mounted wall box following local electrical codes. Before beginning installation, disconnect power at the circuit breaker.

After wiring, fix the switch to the box with the provided screws and attach the cover or frame. Restore power and test the switching function to confirm correct operation.

Recommendations

Use this single-piece thermoplastic switch for general lighting circuits with compatible voltage and current ratings. Verify compatibility with existing wiring and mounting depth prior to purchase. For installations involving dimmers, multi-way switching, or where higher ingress protection or fire-resistance is required, select a product specifically rated for those functions. If unsure, consult a qualified electrician to ensure safe and code-compliant installation.
