I need a push button Normally open switch

Geo-TH,In · Feb 6, 2023

This 30 year old garden tractor has a gremlin in the ignition switch.

The starter won't work. I hear a clicking sound when I turn the key to start, no starter.
I easily applied 12v to the starter solenoid and the starter worked just fine.

JD has a complicated ignition switch that plugs into a multi pin plug. I think either the plug is oxidized or the ignition switch is bad. Dang gremlins.

I need to see if I have a used push button switch or buy one.
A PBNO would make the repair easy.
No kids will be driving this garden tractor.
I'll look for a 12v wire coming from the ignition switch so no one can accidently push the starter button.

Do you have a recommendation for a (cheap) push button switch?

John Deere offered a had start kit for mowers that uses a start relay in it to make it work better,

as far as kids driving it if you find a wire on the key switch thats hot only when the key is turned on then you wont have to worry about the starter being activated accidently.

Sounds like you need a starter button for an early Massey Ferguson gas tractor.

The switch is a weak part on the John Deere LGT's. Aftermarket versions of that ignition switch are available at auto pars stores or online. There is a site called Isavetractors that has a lot of stuff.

Correct description is "momentary contact switch".

If you really want to bypass the safety's, then just come off the start position of the existing switch and go directly to the starter solenoid.

Switch---Go to Surplus Center.

Before you do that though, Clean all the safety switch connections. I had a Deere mower that would do exactly what you are describing. It had 4 safety switches after the ignition switch. After I cleaned up all the connections, it worked like it should. You get a lot of voltage loss through all those connections if they are dirty or corroded. After that, it just became an annual maintenance issue. Good Luck.

gene i just called and told him about the kit and how he could build his own for less all it takes is just MORE current to that trip wire and the thing will start.

JD came out with a relay kit for the older lawn mowers. Maybe that is all it needs ?

John730D · Feb 6, 2023

I forgot to list the safety switches. Seat, Parking brake, PTO, Neutral switch.

FWIW I classify such as Spring Return to Normally OPEN, Momentary Push Contact CLOSE, but I've seen many other such similar descriptions. As long as its Voltage Withstand rating, Current rating and necessary weatherproof is adequate it should be a cheap simple readily available item on Amazon or E Bay etc. See if any other sparkies agree ??

You got this easy peasey

The ih tractors use normally open switch . From the 60 series and 06 series also as an example. It is rated for the starting current.

I'm thinking you hit the nail on the head..
A safety switch is my gremlin.
A PBNO will wire around the switches.

Geo-TH,In · Feb 6, 2023

Thanks. That looks like a nice switch.
That gives me an idea to visit RK this morning.

Good deal jm, all it is is just a cube relay in a socket plus some wire. The relay can operate at a lower amperage to kick in the start relay.

Off to TSC

Cambridge Push Button Momentary Switch, 20A, 12V DC
$6.99

Maybe the only the high amperage contacts in the clicking solenoid need to be filed and cleaned?
