"This switch is a good quality product that is smooth to operate when assembled correctly. The previous switch was difficult to operate and eventually failed. If the switch is sticky in operation take it back as it is faulty."
"As a professional electrician, I need my customers to feel confident that I am installing good quality gear. Unfortunately, in the last couple of years I have had a few of these switches fail (even new ones straight out of the packet), which makes me look bad. Used to love MK, but the quality seems to to have deteriorated lately which is a shame."
"My bathroom is absolutely stinking of sweaty body - mine! The existing generic switch packed in and I couldn't get a shower before going to work last night. I bought the new MK one on my way home and it has just taken me 35 minutes of arm-aching work to fit a simple switch to existing cabling - a job that should take less than 5 minutes.
It is rated at 50 Amps, so the manufacturers should expect 10mm square cables to be connecting with it, but they obviously didn't measure the inside diameter of the shared single earth terminal hole while it was on the design bench. Talk about trying to cram a square peg into a round hole!! Doing this up near ceiling level in a claustrophobic bathroom was guaranteed to turn the air very blue. I am now going to have to use some of that aromatherapy shower gel designed to help you unwind and de-stress yourself.
The nylon cord is very stretchy compared with the cord on the no-name brand that packed in, and if the truth be told I don't think the build quality is even as good as that generic switch with TWO earth terminals I have just replaced. We'll see how long this one lasts.
MK didn't think this one out properly, and it is very annoying from an otherwise excellent manufacturer."
"This appears to be a nice smooth action switch, only issue I found (and as mentioned by previous review), there is only ONE earth terminal. As it is an MK switch and therefore supposed to be top of the range I find it very disturbing that the design has not been thought out. The switch has only been in position for 2 months so I have only given average ratings."
"The switch seems solid enough, however one major annoyance is with the earth terminal. There is only one, so it is quite a wrestling match trying to get two 10mm earth cables into one terminal. - The noname switch it replaced had two terminals and was very easy to wire.
"I am about to go back to Screwfix for the fifth (yes 5th) time to get a replacement. Every one of the previous 4 switches have been MK but the 5th won't be. After about a week the led light would only work if you pulled the cord 3 times and as time progresses the pull mechanism becomes so stiff you can nearly swing on it before it clicks on. Also 3 of the 4 have burnt out internally, my shower is a new 10 kilowatt Triton with all new wiring and my electrician said it can only be down to being a poorly made switch. Can't believe a MK product can be so bad, my father in law will be turning in his grave, he was an old school sparky and would only fit MK."
"I purchased this as an exact replacement for a unit i purchased from Screwfix previously. As it was past a year old, i could not exchange and had to buy new. I only have a 8KW shower with 10mm cabling and it burnt out in just over a year, so if it does it again , i will but a nother make. There are cheaper ones around but i thought this was a quality product so paid the extra. Lets wait and see."
"I don't believe MK can make these, they must be just branded MK. I have had to change about 5 in the last 5 years, the rotary indicator jamms up and at best you have to WD40 that part of it. Also one earth terminal is a poor design, would have expected better from the top manufacturer."
"MK has a reputation for quality - this is the reason I chose this brand to replace a failed inferior product fitted by a Contractor. The shower is used once a day and the power is turned off after each use. Now after approx six months it crackles when switched on. The shower is not heating water when the switch is operated so no significant current is being switched. A second switch pull is necessary to give a 'clean' contact. It will be replaced as soon as I find a better quality switch that will fit the square box."
