⚡ At a Glance
- • Switch Capacity: 275 A continuous at 12V, 455 A intermittent at 12V, 1250 A momentary at 12V
- • Best for: Owners of cars, vans, caravans, RVs, trucks, UTVs and marine boats wanting a simple master shut-off
- • Not ideal for: Motorcycles
Two-position manual on/off switch for DC 12–48V systems with heavy-duty current ratings. Two mounting holes accept 10–12 mm screws and construction uses durable materials for long-term use.
Extended battery life, thanks to manual isolation for 12–48V systems
Manual two-position on/off switch physically interrupts the circuit, isolating batteries from auxiliary loads when parked or during storage. Disconnecting the battery prevents parasitic drains from accessories and control circuits.
Reduced parasitic drain keeps batteries charged for longer, delaying the need for frequent recharging or early replacement. Particularly useful for seasonal vehicles and long storage periods.
Emergency safety cut-off, with high momentary and intermittent current ratings
Current ratings are specified at DC 12V: 275 A continuous, 455 A intermittent and 1250 A momentary, allowing the switch to tolerate brief high-current events. Two-position operation enables rapid manual isolation during faults.
Quick power shut-off helps limit damage during electrical faults and simplifies emergency isolation. Appropriate for applications where occasional high inrush currents occur, such as engine starts.
Versatile installation, with multi-voltage compatibility and common mounting
Rated for DC 12–48V systems and supplied with two 10 mm diameter mounting holes sized for 10–12 mm screw connections. Compatibility covers a wide range of vehicle and marine installations.
Fits into typical battery bays and service panels on cars, vans, caravans, RVs, trucks, UTVs and boats, making retrofit straightforward. Avoids complex rewiring and suits users seeking a simple master shut-off.
