Rated 1 out of 5 by from Poor quality product. I purchase 2 of these switches and the terminal retaining screws were very tight requiring so much force to tighten that the screw threads started to strip and didn't hold the wires securely in place. Previously I always purchased MK but their quality seems to have taken a dive.

Rated 4 out of 5 by from Confused Fitting an intermediate switch should have L2 as top connections and L1 as bottom connections for some reason it had L1 on the left side and L2 on the right so had to go to old format in my mind to make it work thanks MK

Rated 1 out of 5 by from broken / poor design Possibly I was unlucky and got a bad switch - but the lower two screws would only go through a couple of turns and wouldn't hold the power cables in place. I had to get a switch from an alternative supplier instead.

Rated 5 out of 5 by from Good product As always a high quality product from MK with a lovely tactile feel to plastic and rocket action. One observation is that the Screwfix website had the incorrect instruction linked to the product. (August 2020)

Can the intermediate switch be screwed off the plate and put into a 2gang plate ?

I am replacing a L1 L2 L3 L4 switch for my 3-way landing light. Is this switch appropriate please?

Asked by: PBarrets
Very good question. I have replaced an intermediate switch on the landing where the rocker switch failed. The old intermediate plate had four connectors, supply and load (blue and yellow - old colours). Following the old switch wiring the system works but only if the intermediate switch is left switched on? Believe I have a pole separator switch which includes earth separators and few, if any, replacement intermediate switches actually have the required four terminals!
