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.
