pms3v

I’m fitting a Fogstar Drift 105ah to replace a traditional battery that I killed over the summer, running it flat. Current system comprises CTEK D250SA for battery to battery and a 100w PV Logic solar panel routed it through a Victron 100/15 solar controller. Initially I had used the CTEK but...

We’ve just gone to turn on the charger supply button in the PMS3V power control system and the red button pinged off and it looks like the sides of the red piece of plastic has broken. Would anyone know how we might go about sourcing a replacement switch and also how to fit it please?
