M.K. Light Switches.

Zoomup
I have just been fitting some customer bought M.K. sockets and light switches; white Logic style.


I do not like the captive screws as they are initially very difficult to turn and you never quite know when they are fully tightened. I also do not like the very shallow light switch terminals that allow wires to come out, especially if twisted together. I ended up using a battery screwdriver to tighten the screws as my hands were starting to hurt.


Others' views please?

    Are you talking about solid conductors, that vid looked like USA, twisting conductors before inserting into terminals makes testing & fault finding difficult, lost count of the times I have disconnected twisted solids and found a broken conductor


    I twisted the 1.0mm2 solid conductors on a three gang plate switch at the common terminals only. 1. Supply  L.+ link, 2. link to link, and lastly 3. link and L. loop out.


    2.5mm2 twisted at sockets are a no no for me.

    Twisting solids of any size is a no no for me, if they are terminated correctly there should be no problem pulling out, if theres a  few its Wago time, in fact if I found twisted solids on a job I untwist and reterminate
