Questions & Answers

Is this a genuine original part?

This is a quality aftermarket battery switch, not a branded original-equipment part.

How do I know if it is compatible?

Check you have room for a round 127.5mm diameter, 50.8mm high surface-mounted switch, and that your continuous load is within 100A at 12V.

Can it handle two batteries?

Yes. It is a change-over switch for dual battery systems and can switch either battery or both at the same time.
