Replace it

It's worn out. Just replace it with a new switch.

Replace it at your earliest convenience. These are the little things that burn down people's houses.

Light switches are not considered a repairable item. They are cheap enough that you can just buy a new one. Look carefully at the old hook up and do the new one the same way. It is a 2 on a scale of 1 to 10 difficulty. 1 would be pouring a glass of water.

Agree. A replacement costs about 79 Canadian cents (including sales tax!) (That's about 65 cents US, or about 33 UK pence!) Always good idea to have a couple of spare switches on hand. A faulty switch overheating at the start of a bank-holiday weekend not comfortable; just when you were planning to visit Auntie Mabel at Bournemouth and no 'electricians' available or even answering their phones! If switch has two wires attached to it it's simpler than if it's got three wires. So make sure the replacement has identical connections; cos the OP did not say how/or for what the switch is used. Switch off the power; note existing wire connections before removing any of them and have at it. If confused by anything, not 'electrically minded' or "It won't work", leave the circuit switched off at the CU (main breaker panel) and get competent help. Better than a 230 volt fire in a wall and insurance companies are not impressed by incorrect electrical work!
