The answer to 'flickering switch' is a flickering light switch is often caused by loose wiring, a bad switch, or an electrical problem in the circuit. Symptoms include the light flickering, dimming, or turning on and off intermittently. Common solutions include tightening the switch, replacing the switch, or troubleshooting the circuit for a more serious electrical issue.
If the flickering is minor and the switch is easily accessible, you may be able to fix it yourself by tightening the screws or replacing the switch. However, if the flickering is severe or the switch is difficult to access, it's best to call an electrician to diagnose and repair the problem safely.
