any universal inj./key switch from a parts store {ie NAPA} will work

I think the main difference between the gas and diesel ignition switches on the 2010 is the diesel can be turned to the left to energize the glow plugs.

Not exactly true

That is NOT true if hooked up in original fashion. 2010 gas used a special ignition switch with a built-in ignition resistor and a built-in resistor bypass system. A conventional ignition switch has neither of those features.

To use a conventional battery-ignition switch with the OEM Deere coil, you'd have to wire in an external resistor and then find a way to have a crank-only resistor bypass IF using the original Deere 6 volt type coil. If a new generic switch is used along with a new high-ohm coil - then no resistor or bypass is needed.

One further note. If the engine has a Delco starter -the solenoid had a crank-only bypass that can wired into. If it has a Prestolite, there is none.

I stand corrected i went looking at switch pics and JD is correct the original switch did have a resistor on the back of it... that switch is on ebay for $36 or like he said you can put a resistor on it and run a HOT START wire from the start solenoid to the coil side of the resistor if it has delco type starter
