HIGH POWER
CUT-OFF's 
(click left)

This full featured rotary switch is designed to be installed between your battery power supply and the electrical system to cut-out the path of current when needed. This cut-out feature is required in most classes of competition as well as an excellent and simple hidden theft deterrent.

This switch has several added features. You can either mount this switch on top of the mounting surface, or below the mounting surface so only the knob is visible.

Unlike many other lockable switches, you can turn the power on and off without having to remove the key, and a third position which removes the keyed knob.

The removable key is significant theft deterrent as well as a huge safety feature when working on the engine to prevent accidental activation of the vehicle's power or starter.

This switch exceeds the power capacities of most other "50 amp" switches. Lesser continuous load capacity switches can resist current flow when headlamps, heater, fans and other electrical accessories are in demand, therefore providing less power to them, and seeing dimmer than necessary headlights.  2.75" x 2.75" x 4.30".
