Rated 1 out of 5 by from why sell just padlock version just sell the normal version without padlock cant buy them from screwfix as constantly throwing away locking kit and padlock mk4859 is what screwfx should stock and sell

Rated 1 out of 5 by from MK FAN ISOLATOR SWITCH Used these three times now and I've had problems with two of the switches. The terminals screws are very tight and screw material poor so heads tend to become damaged quickly. I wouldn't use again even though I am a great lover of MK gear normally.

Rated 5 out of 5 by from Quality You get what you pay for with MK, quality! Well built and feels solid. Good terminals for connecting. Little pricey but like I say, you get what you pay for.

Rated 5 out of 5 by from Good quality We've installed the switch, it looks good and has a nice positive click. Does what we expect. No idea how reliable it is - it's working now and we expect it to continue to do so.

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?
Asked by: saltyzip
I have this isolator switch on my boiler so I can't see it being an issue. A lot of boilers require a permanent live, a switched live and a neutral so a three pole isolator will be perfect for the job. It would still be fine if there was just a live and a neutral supplying the boiler.

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.
Asked by: desperateforasolution
It cannot be locked in the 'on' position. It can only be locked in the 'off' position.

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

Asked by: Ymmel
You would need a one gang dry lining box with a depth of 35mm.

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
