Hiring a professional licensed electrician to diagnose and replace a faulty, worn-out, or arcing residential wall light switch typically costs between one hundred and two hundred and fifty dollars, which accounts for standard service call diagnostic fees, local labor rates, and the cost of a standard single-pole or three-way toggle switch. If you purchase the replacement switch online or at a local hardware store and perform the installation yourself, the raw hardware generally costs between two and ten dollars. You can evaluate pricing by comparing retail parts costs to local contractor service quotes. You can verify fair value when shutting off power at the breaker, wiring terminal screws securely, and installing the new switch ensures safe, responsive lighting control without flickering or heat buildup.
