    Im in need of a substitute for the brake warning switch on a 1210 pickup. Its IHC part number 352663C1. I have some feelers out for a replacement but it would be nice to find a substitute thats still currently available.

    Which switch? The switch under the dash or the one under the hood? The switch that goes to the master you can try taking it apart and cleaning it. Done that many times.

    The same switch was used in Scout II drum/drum and Scout 800 models. Unfortunately, that commonality doesn't help with the availability of replacement switches. The switches themselves don't look as though they can be disassembled.

    Rock Auto lists WVE/AIRTEX/WELLS 1S6605 as a replacement, but it looks nothing like the original...and at a price tag of $60.79, I'd want to be damn certain it worked before I bought. Even then, that's a lot to spend on such a rinky dink little part.

    No confusion on my part. I agree with you that the valve is the entire assembly which includes the switch. The subject of this thread pertains specifically to the switch.

    That may be, but it is listed and described as being a pressure warning switch. If it was just a stop light switch, you'd think it would be listed and described as such.

    Edit...It only has one terminal. Stop light switches have two terminals.

    Sorry about that; I somehow misread his number, which is strange because some of these numbers I recognize. I removed the misleading posts.

    I'll go to Napa and have them cross 1S6605. Then we can try it right there. For that matter, we can play guess a part and see if we can find one. I don't see how the 1S6605 could work, it seems to be missing the little plastic button mine has. I also have some feelers out to my list of CaseIH dealers to try to find an original.

    The distribution block has some springs and pistons, when one side has significantly less pressure than the other, it trips the switch. IH called it a "Warning Valve"

    The airtex wells part listed an IH pn. I looked that up, and it seems to be for airbrakes. I think that is a low pressure warning switch to tell you your accumulator tank is low and your air brakes are about to fail.

    the tip of switch is broken off inside the dist block. The dist block itself is in pretty good shape. Some rubbing alcohol unstuck it and dissolved the crud. Now I just need a new switch.

    I have looked for these with no success under the IH p/n 352663C1.
    Item 3 in the photo, p/n 352663C1,... I think Wagner is the manufacturer.
    It cross references to Federal Stock Number (FSN) 5945-00-461-9285.
    You could try to source it under that part number.
    When the hydraulic brake valve trips, the little probe from the switch extends deeper into the valve.
    To properly reset the valve, the switch must be removed, the valve is reset, (internal pistons centered) then the switch is reinstalled.
    Failing to remove the switch when resetting the valve breaks off the little probe from the switch, which leaves the brake warning light "on" forever.
    The solution is to replace the switch or disconnect the electrical connector on the switch.
    The brake valve can be easily disassembled, cleaned and reassembled. Two new o-rings and two new copper crush washers are all that is need to refresh the valve.

    I agree, it is a pressure switch and not a stop light switch. Another contributor had some confusion regarding the subject of this thread. He subsequently deleted the posts that he later felt might be detracting from the discussion.

    That switch was also used on the Ford Falcon cars and possibly the full size cars. Only difference was the Ford version had a different electrical connection.

    There doesn't seem to be a listing for that switch either, unless you know of one.

    I seem to recall there being a thread about the switch within the last few years; might be worth searching for it. The number is listed on some of the NSN sites, but I doubt they are worth checking. Nevertheless, here's one I don't remember seeing before:

    If you do try it, use a disposable address, ask for quotes on five each for both the switch (352663C1) and the valve (352664C91) :beer:

    I'll bet it would be fairly easy to jury-rig a switch using a brass fitting with the correct thread to fit the valve.
