Fair price check
Our price is the manufacturer's home-market RRP — what this gear sells for where it's made. Branded marine equipment in Thailand typically retails 15–90% above that, when prices are published at all. Ours doesn't.
About this product
These are the heavy-current switches at the heart of every Merlin management system. Being bistable they pull current only for the instant of transition between on and off, so they add no standing load to the batteries, and their IP66 housing lets them mount next to the batteries in a wet locker or engine bay. Choose 200 A for most 12 V and 24 V banks and 350 A for large house banks, thrusters and emergency-parallel circuits.

- IP66 sealed for battery-locker mounting
