MK 10A 3-Pole Lockable Fan Isolator Switch White is rated 4.2 out of 5 by 5.
Rated 5 out of 5 by from Switch A good quality product but do I really need the locking device? Sure I can see some circumstances where an electrician might find it handy so why not offer this as an extra and keep the basic price down.

Rated 5 out of 5 by from Fan Isolator This is a quality product. The terminals are clearly marked and easy to make off. The one I received was complete with an isolating plate and padlock, which justifies the higher cost. MK products aren't the cheapest but you do get what you pay for and when you can install knowing you don't have to go back it, it is worth the small premium.

Rated 4 out of 5 by from Good quality isolator switch Again, needed to get an MK to match with existing. Price was much higher than competition. Otherwise excellent.
