Faulty Light Switch Diagnosis in Singapore
Faulty switch diagnosis starts from $80 at SG QuickFix. A switch that sparks, buzzes, feels warm, works only sometimes, or controls nothing is checked to see whether the switch itself has failed or the fault lies in the wiring or the light. Most diagnoses take 30 to 45 minutes.

Task guide
When this may be needed
- The switch sparks or crackles when pressed.
- The switch is warm to the touch.
- The light works only if the switch is pressed hard or held.
- The switch clicks but the light stays off with a working bulb.
- A switch in a multi-gang plate has stopped responding.
What the team does
The technician tests the switch and the light it controls. With the circuit isolated, the switch is removed and its connections checked for looseness, burning or corrosion. A loose connection is remade; a failed switch is priced for replacement. If the switch is fine, the fault is traced to the light or the cable between them.

FAQs
A warm or buzzing switch usually has a loose connection or worn contacts, which can overheat. Turn the light off, stop using the switch and have it checked.
A small spark inside when switching can be normal, but visible sparking, crackling or burn marks mean worn contacts or a loose wire.
Switches are connected to live wiring. Singapore's regulations require electrical installation work to be done by a licensed electrical worker.
