Crabtree switches
 

Can anyone comment on the life expectancy of Crabtree grid switches?

I fitted two intermediate switches in a grid mount about 2 1/2 years
ago. I am just about to replace both switches and grid with a Contactum
twin-gang intermediate switch as the one of the Crabtree grid switches
has failed for the fourth time, i.e. both grid switches have failed
twice.

IMHO at nearly £10 a time this is unacceptable.

Does anyone have a link for Crabtree?

Did a quick search on Google and found it ....

Personally I prefer MEM grid switches.

Hi

No experience of Crabtree, but I was about to ask something similar re
MK equipment.

I've had a dimmer switch and pull cord switch fail in less than a year
each. MK replaced the electronic dimmer without question, but it was
still a pain.

I've bought a no-name replacement for the pull switch for £2 rather
than mess around getting the MK one replaced.

Is it worth buying allegedly decent kit? The mechanical action is
often nicer, but if it packs in after a few months its heaps of
hassle!

The action of the Crabtree switches and the actual 'feel' - no sharp corners etc - was much
nicer than the 'no name' alternatives but if my Contactum switch last the same length of time I
reckon that it will be at least twice as good as the Crabtree switch. This is because the
Contactum switch cost £10 whereas each Crabtree switch cost £10.

It must have gone downhill, then, along with the poorer looks when they
changed design a few years back. I've got the previous 'Classic' stuff
throughout the house including grid switches with not one failure, and I
used to use it near exclusively when I did wiring semi-pro, again with
100% reliability. Not the same with MK, though, although the number of
failures were so small as to be insignificant.

I maybe should have added the word "Now" at the end of that sentence, as
Crabtree used to be good quality, but that was back in the seventies and we
used it a lot. Now they seem to be trying to live on past reputation, as a
lot of once good manufacturers are. I seem to be finding a lot more of that
now'a'days.

It's not actually the switch which fails, but one of the little lugs
which hold the rocker onto the switch. If you can be bothered, it's
cheaper to buy 1gang1way switches and carefully swap the rockers.
Done this to upwards of 50 of the little buggers in a hotel! Crap
design on Crabtree's part I'm afraid.

I have had lots of problems with MK dimmers - most fail very soon after
warranty - work as a switch but don't dim.
2 fitted in my place now don't dim.

This is usually caused by a bulb shorting when blowing and taking the
triac with it. So the dimmer no longer dims, but just passes volts at full
level.

Yup. been there, done thgat.

Problem is blown TRIAC. Easily replaceable, but do it with a bigger one.

In my case manufacture kindly sent ugraded new guts 'we found that
candle bulbs blow them all teh time when they go sir'
