A light that stays on regardless of the switch position is unusual, and while it is often not immediately dangerous, it points to a wiring or switch issue that needs proper diagnosis. Here is how to think about it, from the licensed electricians at EZSMART, serving Toronto and the GTA.
A switch that no longer opens the circuit properly can also indicate arcing or degraded contacts inside, which can lead to heating and, over time, connection failure. Replacing the switch is typically inexpensive, but the diagnosis should be professional. Any switch replacement should be performed by a licensed electrician in accordance with Electrical Safety Authority standards. Quality replacement switches from manufacturers like Leviton or Legrand are standard options.
Is it safe to leave a light that will not turn off on until an electrician comes?
Usually yes, though turning off the breaker for that circuit is a reasonable precaution.
Could this be a bulb issue?
Only for smart bulbs, since a regular bulb has no ability to stay lit if the switch has opened its circuit properly.
How much does replacing a failed light switch cost?
Replacement itself is inexpensive, though a service call minimum typically applies for a licensed electrician\’s visit.
