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.


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

Personally I prefer MEM grid switches.
