Spartan Power Battery Switches Editorial Review
The Spartan Power Battery ONOff Disconnect Switch 300A Black Ignition Protected RV Marine is a great product for those who want to safely disconnect power to their inverters. The switch is well-made and sturdy, and includes four sheet metal screws to simultaneously seal the case and mount to a surface. The switch includes a hexagon shaped cutout under each screw hood to hold nuts without a wrench, but the 3/8-16" nuts needed are not supplied. Although some customers found the switch too large for their application, it was perfect for others. The switch is easy to install and functions as advertised.
