"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 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."
