"I only bought this product as Screwfix do not hold the MK version in stock and I did not want to make another trip the following day to collect the MK one.
The LAP switch is cheaper but inferior: the quality of the plastic and the screw connections aren't a patch on the MK Logic range. Also, I had assumed that this switch would have a cable outlet in the bottom edge but it does not. Nor does it have a cable clamp whereas the MK switch has both.
I've also noticed that this switch really arcs when switching off a 3kw immersion heater and the blue flash is clearly visible through the filter over the neon.
