MK 1-Way 20A DP Grid Switch White is rated 3.9 out of 5 by 11.
Rated 5 out of 5 by from Versatile switch 20A metal clad complete switch units are not available only 10A ones. The grid system allows you to build just the 20A switch you require, great system.

Rated 4 out of 5 by from MK Grid system Good system to allow you to make up unusual switch combinations on a single face plate. Bit more expensive than other such systems but also seems a to work a little better. So you get what you pay for.

Rated 2 out of 5 by from Grub screw failure During installation found one terminal screw was seized up and would not turn. Unable to complete the job. Luckily I had not discarded the old switch that was being replaced and could reinstall it. Had to wait for Screwfix to send replacement by post to finish the job. N.B. I had found 'sticky' terminal screws in previous grid switches but these loosened with forceful persuasion so they could be fitted. The quality of these items are noticeably inferior to the 20 year old versions being replaced!

Rated 5 out of 5 by from Good product, could be better Like previous reviewer, I was replacing an existing switch set. Because I could not get an exact match for one switch I had to replace the whole set. I shall review the switch and frame separately. I also feel the screws are in an awkward position. When installed into the frame they are inaccessible. With 20a cable, they are difficult to get back into position, but doable. Overall I am happy with the look and

Rated 4 out of 5 by from Nice quality, matches other MK Reviewing this along with the grid frame as the 2 have to go together. Nice switching action, well made, looks good, matches other MK and at a reasonable price for the 3 20A switches, frame and white front plate to replace a cheap and ugly one already there. One slight annoyance is that the terminal screws are covered by the frame when the switch is inserted. This means the terminals have to be tightened with switches separate, and when linked with 2.5mm cable it can be a struggle to get them in. Would still buy again, but MK could do with moving screws backward or making the frame a little thinner so screws can be accessed with it assembled.

Rated 2 out of 5 by from One ok one not Had to get two of these recently for a job. Once on site found out that one of them had a seized terminal screw. Very annoyed to have to go and find a replacement costing me time and money. Maybe MKs product quality control is not what it should be. They used to be a brand you could rely on.
