John Deere AR58126 is the key start switch with blade terminals and two keys. It is used on John Deere crawler dozers and backhoe loaders. 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.
The same part is also sold as John Deere AT195301 and John Deere AR47458.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Machine will not start or power up
A worn key or selector switch is a common cause of no-start faults once the batteries and fuses check out.
Intermittent faults
Switches that have to be held or jiggled will fail completely soon. Replacing them is a quick job.
Water and dirt
Cab and dash switches take water and dust. A corroded switch is cheaper to replace than to chase.
Fleet spares
A spare switch for each machine type keeps a machine working instead of waiting for parts.
