Small Engines (Lawn Mowers, etc.)/Replacing riding mower ignition switch


I have a Honda HA4118H38A lawn tractor which won't start. The ignition switch has failed and I'm looking to find a replacement switch. The old switch was soldered to a circuit board, I've removed it and have been searching the web for a switch that will fit in it's place. No luck so far (the switch and circuit board together cost close to $200). The switch has 6 terminals and 3 positions and no ID except Indak with patent numbers. Any ideas of where I can find a replacement switch will be greatly appreciated.

That will be very difficult to find.  I'm betting Honda has an exclusive deal with the manufacturer.

Can you ohm the switch to see which pins connect as the various positions, start, run, off?

If so, you may be able to adapt this switch:

Did you check Indak's website?

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
