Hmm, something wrong here !

OK, response from the manufacturer is pretty much as guessed - it's to do with illuminated switches.

The fuse is placed before the switch on all of our fused switches. The reason being, if the fuse blows on any switch with a neon indicator this will extinguish in this set up. If the fuse is after the switch it will still illuminate causing confusion.

As you say - as you expected. However, what they say is obviously only correct if the neon is wired (I would say 'incorrectly') to the switch output - rather than to the output of the whole accessory.

Kind Regards, John

Obviously, in a "grid" type setup like these, that will be the case unless the switch has separate contacts for the indicator - which is something I've rarely seen.

Indeed so.

.... - which is something I've rarely seen.

Same here - but IIRC I have actually seen it in my time. However, as I said before, IMO the 'correct' grid/modular realisation of a switch+fuse+indicator usually requires 3 modules.

Kind Regards, John
