Switch contacts melting

Post by Mike3779 » Mon Sep 10, 2018 2:40 pm

Hi,, basically my wall double socket stopped working, so i opened it up to see what was cauusing it. I found that the plastqic bump on the rocker switch had melted flat mean the contacts werent being pushed when turned on.. This has happened on a fewsockets usually when using the iron or kettle after many uses. They ar Mk sockets.. Is this a usual problem ir should i test the cables etc.

Test the cables for what?

I would be inclined to change the plug on the iron, and always unplug the iron, don't worry about the socket switch when ironing, leave it on, or better still get sockets with out switches

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

I mean surely these switches shiuldnt melt due to the power being drawn by the iron.. Its not tripping the fuse box so it not like its drawing extra high,, so just curious why this is happening.. Thought mk were thw best brand... Maybe not then

No moisture issues. Guess they could be fake,, they seem different than the video.. But the vid has the same sprung plastic plunger that contacts the switch. But like u said arcing from switching on and off is what is doing it.. From memory i thiight this was just a voltage spike not necessarily much power to melt.. But guess im wrong hence the melted part:). Thanks for your help guys.

Switched sockets go back to the old days of DC power when they were needed. You can have unswitched sockets in your kitchen if you want to.

Going back to what has already been suggested.

Long story short. Friend had problems with plug/socket getting warm with Kettle plugged in. I looked at the plug - cheapo brand. Changed the plug - problem solved.
