Rated 3 out of 5 by from OK but things to watch for MK used to be a reliable brand but no longer. The screws in the new series are not as good and wires can appear to be secure when they aren't. There is no earth connection available so you need to use a back box connection or a separate connector to maintain earth, the switch is on when pressed in at the bottom and isolated when in at the top, opposite to a UK light switch and there is no warning red colouring on the switch. MK make one without the lock-out but Screwfix don't appear to stock it. Still it is a neat isolator switch if overpriced compared to other makes.

Rated 5 out of 5 by from Usual MK quality Got this to replace a cheaper brand switch that had broken down. Simple to fit and is a better match to the other switches. I'm sure the enclosed safety bar and padlock are useful to some, but it would be good to have the option of just buying the switch.

Can I use this to replace an existing legrand boiler isolation switch?

I currently have a legrand isolation switch with the markings boiler on it that isolates my ideal boiler from the electrics that is damaged. So the question is would this switch be a suitable replacement please?

Supply / load

The switch does not seem to have load or supply sides, does it matter which way round it is used?
Asked by: Diva
No it doesn`t.

can this be locked in the on position, or only in the off position?

I have a tenant who persists in switching off bathroom fan with mould and damage to flat. I imagine this is a common problem. This could help if it can be locked in the on position until unlocked for maintenance work.

What type/size of back box does this require to fit to a stud wall?

Asked by: Ymmel

How does the MK locakable isolator lock. I can't see any access for a padlock

Asked by: NoneofHorley
there are 2 dimples on the side of the switch when rocked to the off position that the shank locates too. The padlock is then offered up to the shank when in position
