Any ideas?

Hi Guys,

Visited a property today where the ELV down lights had stopped working, 9 in total. Carried all the usual checks but still couldn't find a reason for these lights not working. After a bit more poking around I found one of these in the circuit which seemed to of failed. I swapped it over with one of two others found in circuit to another two set of lights & we were back in business.
Never come across one of these before, can anyone shed some light please.

Depends what lights are fitted....if there are 9 x 50w halogen, then you are over the rated limit of the electronic transformer

Thanks guys, very much appreciated, switches were of the modular push button type, didn't think they were rotary dimmers though.
