Ford 1720 Ignition switch

The short answer is the two switches really are not the same part. As noted above the NH is more robust to carry the glow plug electrical load. Also the NH switch is likely in "service" production, which means run quantities are much lower raising the cost to produce. Cost to produce a service part in automotive industry is 2X-5X to produce same part in service mode as opposed to when car was being assembled.

Too right! It arrived today and has different terminals... the OEM switch has screw-ons (ring terminals on the wires), the replacement has spades.

That sure stinks.I wonder if they make a ring to spade connectors I looked on radio sahck and couldnt find any.
One ide would be to use the spade and a ring and a short piece of wire between them. Or possibly connect them directly together and solder.
Either way It would be nice not to have to cut the wire..
Let us know what you choose.Oh, didnt they state the type of terminals in the description

Nope, no description of the terminals in the online catalog. Caveat Emptor, I guess.

Agree, don't want to cut those wires! Fortunately it turns out the switch is OK after all (see thread about Electrical probs). If I did have to use this one, I might try drilling out holes in the blades and get backing nuts for the little screws, before trying to fabricate some adapters.

Is there a tractor supply near you? I found a ford 5 position switch on the shelf there for $24

I think I'd just but a ring and spade togehter and hit it with a lil solder before going to the trouble to drill out a terminal and then add a nut.

it's just a switch...

Kubota 66706-55120 is exact replacement. Purchased from Messicks about $35.00. Hope this helps someone. Used on 1988 1720 2WD. Wiring harness has two connectors that enables one to take the ignition switch to the bench to switch the wires.
