What could be causing this?
A switch that fails, sticks or sparks is more than an annoyance — it is a warning. These are the most common causes we deal with every day.
Worn mechanism
Thousands of operations wear out the spring and the internal contacts. The switch stops responding or gets stuck halfway.
Poor contact on the wires
Loose connections behind the faceplate heat up and cause sparking or crackling when you turn the light on and off.
Damp in the wall
In bathrooms, kitchens and external walls, damp corrodes the contacts and can cause small shocks when you touch the switch.
Old installation
Switches from earlier generations are not built for today’s loads and do not meet the safety standards in force.
What to do right now, while the electrician is on the way
Simple steps to protect your home and your family
- 1
Stop using the switch
If it sticks, gets hot or sparks, do not keep forcing it — every use makes the damage to the internal contacts worse.
- 2
Switch off the circuit if there is sparking
Visible sparks or a burning smell: switch off the lighting breaker in the consumer unit until the technician arrives.
- 3
Do not open the faceplate
Even with the light off, the wires behind the switch can still be live. Opening it is a job for the electrician.

Frequently Asked Questions
Do you repair or replace the switch?
It depends on the state of the mechanism. Whenever a repair is safe and lasting, we repair it. If the wear compromises safety, we fit a new switch — we carry the most common models in the van and the price is given before we start.
The switch gives me small shocks when I touch it. Is that serious?
Yes, it is a sign of earth leakage — usually from damp or a wire touching the back box. Stop using it, switch off the circuit at the consumer unit and call us: this is a priority situation.
Can you replace several switches in the same visit?
Yes, and it is the most economical option: there is only one call-out. Many clients take the opportunity to renew all the switches and sockets in one room or in the whole house.
Do you do the replacement the same day?
Yes. A faulty switch is resolved on the first visit in the vast majority of cases, usually in under an hour.
