Bought this for my van conversion to sit between the vehicle battery and leisure batteries.
Easy to install and works perfectly and now if anything goes wrong I can isolate the batteries 👍


Thanks for the feedback Mark

I bought two switches, one each for the leisure battery circuit and the starter battery circuit. East to fit and appear to be good quality, robust and should do the job.

Solid & well made - does the job

I didn't need such a high current carrying capacity but I didn't want the removable knob of the lighter duty version so I bought this one and I like it apart from the shiny silver picture of a battery in the middle of the knob.

very good service
