301A Brake light switch

ET · Oct 27, 2014

I have a 301A here at work that is equiped with brake lights. The presure switches switches are screwed into the rear axel housings and ported into the brake piston oil. I can't find the switches or the adapters from o-ring fitting to 1/8" pipe thread. Can anybody help me out?

Does parts keys 23-27 resemble what you're looking for? I realize this isn't a brake switch but the JD brake switch I find has no o-ring.

You could use this switch parts key 11 AL67715 on brake valve

The switch is 1/8" pipe thread, the part I realy need is the adapter that goes from the the 1/8" o-ring to the 1/8" pipe thread without being so bulky that it gets broke off. The hole it screws into is one of two identical holes in the axel housing that the oil line from the pedal valve goes to. My parts book shows a plug in the extra hole. This is a state roadside mower tractor and came with the brake light setup on it.

Did you look at parts key 23 in the 1st photo?

Part 23 doesn't have an o-ring on it where it screws into the housing. It looks like the o-ring is on the switch.
