100A Continuous Rating Waterproof and Dustproof 2 Position ON OFF Marine Battery Disconnect Switch Battery Isolator Switch

The NEKEKE MT097 is a master battery disconnect switch built for owners who need a dependable way to shut power down completely before storage, service or emergency situations. Rated 32V DC with a 100A continuous current capacity, it covers the everyday electrical demand of small to mid-size boats, campers and off-road vehicles without adding bulk to the dashboard or battery compartment.

The switch works on a simple two-position principle: turn to ON for normal operation, turn to OFF to cut the battery loop. That single movement removes the slow drain caused by bilge pumps, radios, GPS units and standby electronics during long idle periods, and it gives technicians a safe, isolated circuit before any wiring work begins.

The body is moulded from impact-resistant material and sealed against splashing water, salt mist and road dust, so the same unit performs equally well on a wet marina dock and on a dusty trail. A threaded collar locks the switch firmly to a panel or bulkhead, keeping the terminals steady even when the boat is running through chop.

• Higher current headroom — 100A continuous rating at 32V DC, leaving margin for winches, livewell pumps and accessory clusters.
• Two-position certainty — a firm ON/OFF detent that stays where it is set, with no floating middle position to misread.
• Marine-grade sealing — splash, dust and corrosion protection suited to open-cockpit boats and exposed engine bays.
• Compact footprint — the short barrel body fits behind narrow dashboards and inside tight battery lockers.
• Threaded panel mounting — a single-hole fix that holds torque under vibration and simplifies replacement of an old switch.
• Visible state at a glance — the knob position tells you instantly whether the battery loop is open or closed.

Because the unit is compact and sealed, it drops into a wide range of 12V to 48V battery layouts:

• Marine — open-cockpit boats, rigid inflatables, pontoon boats and small yachts needing a master cut-off before mooring.
• Recreational vehicles — motorhomes, camper vans and trailer caravans where house batteries sit idle between trips.
• Off-road and powersport — ATVs, UTVs, side-by-sides and dirt bikes stored for long periods.
• Automotive and workshop — cars, light trucks and generator sets that need a service isolation point.

1. Disconnect the negative battery terminal first, then the positive, before touching any wiring.
2. Choose a dry, reachable spot on the panel or bulkhead that allows the knob to turn freely through its full arc.
3. Drill to the barrel diameter, insert the switch, then tighten the threaded collar until the body sits flush and cannot rotate.
4. Route the battery negative cable to one stud and the load side to the other, and check that both nuts are torqued down.
5. Reconnect the battery, turn the knob to ON and confirm the circuit with a meter before returning the vehicle to service.
