What Are The Risks Of Modifying The Structure Of A Wall Switch?

The most common problem when modifying a Wall Switch is incorrect wiring of the live and neutral wires. Connecting the neutral wire to the L terminal of the switch or confusing the wiring positions can cause the switch to malfunction or generate unstable current. Poor wiring contact can lead to increased temperature, and prolonged overload can cause short circuits, easily resulting in a fire. Furthermore, exposed wire cores and moisture intrusion can accelerate insulation damage, directly threatening residential safety.

Installing wall switches by drilling grooves in load-bearing walls can damage the reinforcing steel and compromise the structural integrity of the building. Improper drilling depth can weaken the wall's load-bearing capacity, creating long-term structural risks. While drilling into non-load-bearing walls has a smaller impact, it still requires adherence to construction regulations to avoid accidentally damaging concealed wiring.
