hi,
the on off button will not stay down it works perfectly well if you hold the button down but it wont stay down itself, the switch is soldered onto a small board with the lights and selector buttons on it this smanll pcb is connected to the main pcb by a ribbon cable an is detachable,
is the switch available or the smal board it is on available,
on the connect site it seems to be part of he main pcb.
thanks.
