I could have sworn that someone posted further back in this thread about a source they found for the switches, or better ones. I can't remember now. It would be like 20 pages back probably... Maybe it was over at ISR...

I think that it was switches for the F1 rim, but not 100% sure about that.

It was me -- same switches for both the F1 rim and the standard paddles, I believe, and the same circuit board, too, just different wire lengths.

Still working on verifying exactly WHAT switch will work (size and form factor, PLUS a long life-cycle / high repitition switch), and once I nail that down, I'll look into producing PCBs that will be like-for-like replacements for the Thrustmaster assemblies, complete with wires and connectors.

So, lots of work to do still on my part. Once I identify a proper switch, I'll make the part number info available for the DIY soldering types.
 
So I tried your fix John but unfortunately it seems my down shift switch is on its way out! After checking the foam and removing the spring there's no sound when switch is depressed and is only working about 50% of the time.pretty useless really, so now I need to replace the switch myself as my warranty is up, but have no idea what sort of switch I need or where to get them from any help would be much appreciated
Thanks Justin

Justin -- here are some recommended fixes for the paddles with the GT wheel from the iRacing forum:

You can remove the wheel trim and the paddle shift assembly, then swap the connectors for the left and right paddle shifters.

If the same paddle shifter keeps acting up, the problem is in the shifting mechanism.

If the opposite paddle shifter starts acting up, the problem is on the mainboard -- either a bad connection where the paddle shifters are plugged in or something else in the circuitry.

I had this problem with one of my shifters. It turns out it was hitting the plastic ring that covers the shifter units and couldn't close the switch. I just removed it since it didn't seem to do anything (keeps out dust?) and it works fine.
 
Not sure if this matches the same form factor, but check out the KSC401J 50SH item -- the data sheet (page 1) shows 5,000,000 cycle operating life:

http://www.ck-components.com/14422/ksc_31aug10.pdf/

I'd like to get my hands on your old BROKEN switches then order some of these to see if they will fit, so if/when you (or anybody else) gets replacements from TM -- or if you have any old, broken ones on-hand -- drop me a PM.

The small PCB looks VERY small, so it might be possible to replicate the boards, procure the 5,000,000 cycle switches, locate the proper connector for the cable, then produce a "long-life" replacement switch kit for a fairly reasonable price.

Carrying this topic forward -- I think the switches I identified will NOT work with the Thrustmaster PCBs because they are surface-mount switches, while the switches used on the Thrustmaster boards use through-hole type solder connections, not surface mount (smt) switches.

Still, I know a long-life replacement exists . . . I just need to search more.
 
Not sure about changing the foam type -- I tend to think that plugging the hole might be the best choice.

From the look of things, the spring is there to provide the resistance and spring action for the paddle; the foam inside the spring is what actuates the switch, I believe.

The spring is double tapered and smaller at both ends, kind of like this:

()

The foam resides inside, so changing-out the foam could deform the spring. Going with denser foam or less "embeddable" foam might turn the paddles into hair-trigger switches, which might or might not be a bad thing.

Anyway, after seeing one paddle start to sound "dead" with no click, and seeing it miss shifts on occasion, now it's been rock-solid and reliable for going on two weeks, I think, so I feel pretty confident that I did stumble across a small and easily rectifiable "issue" here.

If (or when?) it happens again, I'm going to try to fill the holes in the switches with plumber's putty, then let it dry well, then re-assemble to see if that stops the problem for good.

This is what the switch assembly and the spring/foam looks like:

I understand the search for a long life replacement, but are you sure Thrustmaster wouldn't supply these as spare parts? They seem to be happy to send out replacement fans and other components that require opening the wheel?

I wonder if that switch is the same through all 5 versions of the wheel

This is why Logiforce and I suggested that Madbeater contact Thrustmaster tech support about replacement parts -- but the problem/fear is that Thrustmaster may not provide out-of-warranty replacement parts forever, so it would be nice to have SOME alternative option.

Very good question about all 5 versions of the wheel. I have a V1 wheel, so it would be interesting to compare parts from my wheel to someone's V5 parts sometime.
 
I believe those are 12mm? You can easily find such switches in any electronics shop.

Sure, if you want the crappy, 100,000 cycle versions that Thrustmaster seems to use as their default part. If you want a more durable version with a higher life cycle (like one that's rated at 1,000,000 cycles, for example), you have to comb through the specs and find the right switch at a reasonable price.

If you find a suitable part before I do, though, feel free to share with us all!

;)
 
This may work: Omron B3W-4055

Rated at 3 million operations min.

It has a square actuator which I doubt makes a difference. $0.57 each from Mouser.

Actually, the B3W-4050 is the one I've been looking at as the closest like-for-like high-operation switch that I've found so far (the 4055 has a grounding tab, which isn't required/used by the stock Thrustmaster part).

http://www.mouser.com/ds/2/307/en-b3w-3995.pdf
 
The 4100 series has the grounding tab, the 4000 has none. The difference between the 4055 and 4050 is the color and actuation force. But... 4050 is the 3 mill. version with weaker actuation force so it's probably a better bet :) I can't really imagine in my head what the difference would feel like in force necessary though... :/
 
I had to order a ton of other stuff today so I added 5 of the 4055 and 5 of the 4050 to my order... The stuff won't take too long to arrive

I'm in the process of laying out a board now, and I plan on ordering a few of these when I place my next order with Mouser. I want to verify that they're directly compatible with the Thrustmaster circuit boards for people who want to go the DIY route, but I also want to be able to produce direct replacements for people who don't want to mess with soldering and such.

:cool:

That sounds like an excellent idea and certainly within your capabilities. :)

You should also be able to buy those wire assemblies cheap as heck, ready made. It looks like a standard JST connector, possibly molex I suppose. It's got the JST look though. JST XH to be a little more specific...

If you are going to make your own... Your options are wide open for the switch :)

Keep us posted
 
Keep us posted please. I have a V1 with a paddle switch starting to act up. Thanks for your research.
 
I couldn't resist the temptation to invert the pedals in the alternative orientation so that they come out of the back rather than bottom of the pedal unit.

All I can say is fantastic! I find I am able to get much finer control over the pedals and it somehow feels much more convincing.

I wanted to get one of those wheel stands like the Omega GT wheel stand (as it has a separate arm for the gear stick), but I believe it only has suitable fixings for the pedals in the floor orientation rather than rear one which is a shame. In fact I cannot see an obvious way to bolt the pedals to anything when its oriented like this.
 
Nice easy mod for a better gas pedal using compression springs, adds about 3lb more resistence compared to stock wich is around 3lb.

I used abt of pipe insulation like this http://www.toolstation.com/shop/p64166?gclid=COOhlPmv-LUCFc3HtAod_mkA2A and its much better :)

Have tried a few different sized bits, 'm on my smallest now, i had a good bit in there, was very hard to twist it in the spring and this is the one that was around 6lb or resistence, i'd think the little bit have in the pic wont do hardly anything as i can still sqash the spring between thumb and index finger.
I'll probly settle with a good squashing as it felt nice.

FWIW as a reference point my modded CSPV2's fish scale at about 5.4 pounds. That is using two springs (a Hillman from Lowes wound into the stocker) and the trunnion in the stock hole but with the pushrod set to cut travel from the stock 2 ¾ inches down to just over 2 inches. With the stock travel the force would wind up about a pound heavier than the 5.4 I'm at now. That is because the pedal would further compress the spring.

So it looks like we wound up liking around the same amount of force. What travel distance are you seeing?
 
The travel is same as stock.
I tried a small bit of insulation, was pffft so gone back to a good decent sized bit.

I think around 6lb seems just right for my style, its not too hard that its hard and its not too weak, it seems just about right to rest a foot on while cornering.


Clutch at 75% travel

Gas at 75%

This

Gives me this :)

largebit_zps7460a7b1.jpg

As the inslation is compacting within the spring the more travel that is applied the more resistence is generated, perfect for resting foot in a zone that does'nt wheelspin when coming out of corners

There's enough room inside the spring for a good sized bit of insulation that will give around 6-7lb at 75% travel, full travel of gas pedal is same as stock.

Brake at 75% is around 15lb+

Still waiting on my second class postage non digi fishscale from fleabay, seems along time ago i ordered it now :(

Hey guys, I noticed last night that the right side paddle on my T500 would not shift sometimes. I have since switched to my THR8S for shifting, which I like better anyway, but I am just curious what you guys think could be causing this and whether I can easily do a fix myself.

Thanks,
Craig

Craig,

John Bodin is working up a solution. However, you can try what he said in the meantime. Getting at the switches is pretty easy. :)

My CSP V2s don't adjust that low in braking force! Check out my Zero Rebound / Quick Release brake damping too on my viddie in the Fana-Mod thread. Feels wonderful.

Looking forward to your T500rs wheel testing when the bits show up.

Sweet :)

Without having taken apart the T500 (don't tempt me!), would a small piece of lexan (0.010" thick) on the foam help? I race slot cars too, we call the stuff "body bullet proof". Basically thin plastic with self adhesive. I use this stuff everywhere as stick-on shim stock (like on the paddles of my home rig's extensions).

Here is what the stuff looks like stuck to the outside of a slot car body (front with the pin through it):
