Hamilton switch... burnt out !

[sythai]

Hi Guys

After bit of advice please....

Called back to kitchen job today, Hamilton light switch we fitted has burnt out?!
Normally decent gear so just trying to make sure nothing we have done (as Client not so friendly on this one.)

Switch in question is powering all the feature lighting which consists of:

4x75watt (240watts being used) & 1x40watt (30watts being used)/ 24v drivers running various LED cabinet lights.

Trying to check back spec of drivers can only find data sheet for 100watt version so be less than this:
Input 1.2amps so well under 10amp rating of switch and even before that it's on own 6a rcbo (new db installed) which would trip if overloaded.
But on spec sheet has inrush current <15amps, could this be causing the prob ? Not something I'm so familiar with being honest.

Hoping it's just the switch

Thanks Sy

Any photos? Has it burnt out around the switch mechanism, or around the terminals?

Is it just me or does the C and E marking look very close together?

Dodgy copies???

Not saying it is, but maybe worth a check.

Edit.

Added photo.

This is what I’ve got to hand… oral B electric toothbrush. CE mark looks to have a space between.

hamiltons have both CE markings (narrow and apart) spread across their range .

I'd be very surprised if an instantaneous theoretical 15A inrush would cause that amount of damage - has it failed open or closed? There must be hundreds of thousands of 10A switches interrupting LED drivers up and down the land without issue, why should this one be any different?

I would be sending it back to Hamiltons for an inspection under warranty to see what they have to say.
