How to Fix a Broken Light Switch?

[NatalieLynn]

Firmly pull the switch panels on both sides outward to reveal the screws, then remove the large switch panel. Use a flat-head screwdriver to gently pry outward from the top and bottom (i.e., between the convex and concave teeth) at the back to remove the middle square switch head. Then, carefully pry open the plastic clips on both sides with a thin blade to expose the contacts and contact plates, being cautious not to dislodge the spring. Heat the sliding column head under the spring with fire to soften it, then shape it into a bullet head and insert it into the spring hole to test if it can move freely. If the contacts are burnt, you can scrape them flat with a blade, and finally, carefully reassemble everything.
