Rated 5 out of 5 by from Nice Switchgear I needed an illuminated switch for a new immersion. This was easy to wire up, terminals set out so it was in top, out bottom (for me). I thought a 25mm back box might be a bit tight but worked ok.

Rated 5 out of 5 by from Immersion switch Decided to replace the origin 40 year old switch as it was getting warm, which is not a desirable attribute for a switch. This fits in the existing 25 mm box and was very easy to install without any adjustments to the cables. Opted for the one with writing on as the switch is remote from the hot water tank. The switch action is positive but easy - very similar to a 5A light switch. A bit pricey but I only needed one.

Asked by: Pete4421
Hello. The dimensions for this product are: Height: 86mm,Width: 86mm,Screw Fixing Centres:60.3mm. Please note the key measurement here is the fixing centres of the screws, which is usually an industry standard, so this product should fit as a replacement. Thank you for your interest in our Crabtree brand.

Faulty Neon

The neon has stopped working on my 12 months old switch. Should there still be power output if turned on even without the neon?
Asked by: Tel1999
Hello. Under normal circumstances yes the neon not working should not affect the power output to the switch/application. Thank you for your interest in our Crabtree brand.

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.
