Old MK Grid

Tim Howard · Nov 27, 2024

I'm sure someone instantly knows...
I have an old style 2 row mk grid box, with 3 switches on each row...the old sort with the metal clips top and bottom.
To best of my knowledge these modules are now only available 2nd hand so I'm looking to change all 6 switches.

Do I need to change the surface mounted box, or is 2 new frames, 6 new switch modules and a new front sufficient?
(It's a surface mounted box)

TIA

I think the new stuff is compatible with the old. If I'm wrong someone will soon say

If you do change the surface boxes, I would just go with 2iff 3 gang switchs on 2 gang plates. My preference would be Click, it doesn't have those daft frames. https://www.toolstation.com/electrical-supplies-accessories/grid-wiring/c802?brand=Scolmore+Click

99% certain the new front plates don't fit the old back boxes as the old boxes are smaller.

I had a similar problem to solve with an 18 gang MK grid switch about 5 years ago, the cost of completely replacing that for a couple of failed switches was going to be astronomical so swapped a 2 gang grid switch elsewhere in the building for a new grid switch to get the switches I needed for the repair to the 18 gang

Thanks - trouble is I did that last time! I don't think I have any old style left now.
