Komatsu 08068-00001 is the key operated battery disconnect (main power) switch with mounting flange, two brass terminal studs and key. It is used on Komatsu -8 series excavators and D65EX-16 / D155AX-6 dozers. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Machine has no power
If nothing powers up with good batteries, check the battery disconnect switch: worn contacts stop the main current.
Batteries going flat in storage
A switch that does not fully break the circuit lets small loads drain the batteries while the machine stands.
Burned or loose terminals
Heat marks or loose studs on the switch body are a reason to replace it before it leaves the machine stranded.
Fitting tips
Disconnect the battery negative first, fit the cables to the same studs, tighten the nuts firmly and refit the terminal covers.
