Rated 4 out of 5 by from Good product at a good price Needed to replace an old switch in a customers airing cupboard which had broken. This was a good choice as it has easy to wire terminals and with two earth terminals, made easy work of connecting. Can't say much about the reliability, but have used many LAP electrical products and none have fail before. Staff at the branch were as usual very helpful.

Rated 5 out of 5 by from Crabtree Immersion Switch I needed this to replace a 13A spur someone had fitted years ago which was getting warm in use. Fitted this instead and its easy to work with as long as you have a deep pattress - 25mm or more. It has 2 earth terminals which made life a lot easier than twisting 2 earths together as you need to in some products.

Rated 1 out of 5 by from Broken before installing Went to install this crab tree switch to a new cable going to a newly installed immersion heater element. Proceeded to carefully remove the knockout portion for the cable entry like with any other socket or back box that requires it - but as the knockout was evidently too thick the whole faceplate just broke in half. Chucked it straight in the bin, didn't try returning it as I would probably be questioned about how it was handled or installed. Probably would of worked just fine as crabtree are generally very good quality, but didn't even get that far as it broke prior to even being offered up and installed.

Rated 5 out of 5 by from Does exactly as described Replaced complicated broken timer with this manual switch. Exactly what was needed for the job. Easy to fit and value for money

Is my new switch faulty if neon light stays on permanently?

Asked by: Jb2494
I would say you have a wiring fault. Possibly the supply cable has been wired to outlet (bottom) terminals. This needs to be checked by a competent electrician who can ensure that wiring is not live, before anything is touched or disconnected. If neon stays lit when circuit is isolated at Consumer Unit, you have a safety issue and even greater care is required.

20a dp control switch or 20a dp immersion switch

Other than the words immersion heater and the neon light what difference is there between a 20 dp immersion switch and a 20a dp control switch? Thanks.
Asked by: Theaustringer
Hello. Both products are exactly the same in terms of their nature/concept. The differences between the two switches are as noted by customer, the neon light indicator and the text “immersion heater” tampo printed onto the front of the plate. Thank you for your interest in our Crabtree brand.

Asked by: TEDSMATE
The neon light above the switch rocker remains on for as long as the product is in use / switched on- as with all products integrated with light indicators. Thank you for your interest in our Crabtree brand.
