Kitchen light switch 2014 Bourton

In my 2014 Bourton the switch operating the ceiling kitchen light is failing (the light above the sink).  It works intermittently if I fiddle with the switch but basically it is knackered.  I have removed the shade.  All the LEDS inside are working fine.  It is just the switch but it seems  to be hidden within the unit.  Has anyone replaced the switch and if so is it an easy job?  I am reluctant to buy a complete  new switch.  Thank you for any help that can be given.  Mrs Jimmee (the lady who had a window put in the toilet of our Bourton a few years back).

Thank you.  Your reply is most helpful.  I’ll get in touch with Mouser.
