Yes, I also searched for that slide switch a good amount of time, but no luck anywhere else. I saw someone online get it from that site I posted and I felt that was safe enough lol. I also got the switches delivered relatively quickly. I'm sure the one you referenced would work as well, as long as everything is identical.
As far as how to do it, I actually referred to a message previously posted back on page 39 of this thread where provided excellent instructions and photos:
Remember, just be careful and patient. In the copied picture below from that post on page 39, you'll see on the bottom left corner what you'll be replacing altogether. Same way you take it out is the same way you place it back in.
Bose wants to thank everyone for the information you have shared with us about your headphones powering on or off on their own or failing to power off and for your patience as we investigated and troubleshot this issue. Please know that we are listening and working to deliver on our promises. We apologize that your QC35s failed to perform as you expected. We also want to express our gratitude to all the community members in this thread who supported each other and worked together to help with workarounds for the issue.
Our investigation concluded that this may affect QC 35I and older QC 35 II. Not every headset will experience this issue, but unfortunately it is not something that can be resolved via a firmware or software update. We are confident that our newer QC 35II headphones will not experience this problem.
If you are experiencing your QC35s powering on by themselves or failing to power off, please contact your local Bose support at http://global.bose.com/. We know many of you had less than satisfactory experiences when contacting support regarding this issue in the past. Your experience with our product and our company is important to us. Our support team has been briefed on this issue and is ready to assist.
Thank you once more to everyone who has posted on this thread. We appreciate your feedback and hope you continue enjoy your headphones!
Thanks for checking in on this issue. However, what can you say if anything has changed. About a year back, you posted pretty much the same thing as far as I remember.
1. You/Bose have suggested as before that it is a hardware problem but have never said exactly what the problem is. With all due respect, is Bose prepared now to pin down the cause which the 'customers' all seem to know or does the problem cause continue to be 'vague'?
2. Has any different directions been given to the phone support people. Pretty much on every incoming call call, the customer out of warranty is told there is a significant cost for an exchange.
As it sounds like a great deal of customers are dealing with this issue with this model (including myself - after only two years), I’m glad I was able to find this post, but saddened (and angered) I will have to perform repairs on a $300 pair of headphones. Has there been no official recall?

I just wanted to add that I am very disappointed of BOSE products. I tried to contact them; was redirected to the local supplier in Singapore and obtained after a follow up email, an answer replying that repairs are not possible and there is nothing else to do after this product has failed and the 1 year warranty has expired.
I just tried this fix after seeing so many positive results and the excellent instructions in this thread. The first few tests are very good - so far no random, power-off connections! I would caution all who try this when you reach the steps involving the switch internals. Watch the switch return spring which is a loose part and can drop and be lost. BE EXTREMELY GENTLE BENDING THE CONTACT PRONGS. They are VERY TINY and are held in place only by the tension which you are bending against and can also pop out. One of mine did and after much initial panic (to find it) I used tweezers and a small scribe to put it back in place. After using tweezers to carefully place the switch internals back inside, the metal plate went back on nicely. Power up was a big relief and I was happy to see the random power-ups seem to have vanished. I will report back after some regular use.
So my bose headphones finally decided to also stop turning off when I tell them to. Since they are 4 years old and we have the rona flying around I don't have the money to "just buy a new one", so... I though what worse can happen, I grabbed the earpiece with the power control from the inside where the cushion is and pressed firmly into the table, after wiggling the switch from 1 end to the other it fixed my problem so far. Just thought that maybe it can work for someone else so I will share my "fix".
The headset was bought by me 2 years ago as 2nd hand and was since then used for at least 10 hours a day, so a well-used headset I would say. I will most likely use this set until bose comes out with qc45 since upgrading to the qc35 II seem like a waste of money to only get an assistant.
I have reached out to the Distributor in Spain (Gaplasa), who will not do anything as I bought the product on Amazon. I gave Amazon a call, they won't do anything either as the product is 2 years and a half (bought in July'17). Other than this community, I don't know who else to contact and I'm not experienced enough to perform the fix recommended by other users.
I used to work at GoPro. When an issue like this occurred, we recalled the product and offered a replacement immediately.
Extremely disappointed and hoping that someone at Bose can read this and direct me to the right person. Thank you.
I'm sorry to hear of the issues you are experiencing with your headphones.
Whilst we are more than happy to offer you troubleshooting steps for your issues we are unable to offer a service through this platform. Therefore, If you have tried all the troubleshooting steps in this thread, I would recommend getting in contact with Gasplas again to see if they can do anything more for you.
Thank you for your fast reply. However, I already talked to Gasplas, which clearly explained that they do not distribute your products to Amazon and therefore can't offer any support. Amazon told me that they buy their stock directly from Bose and they're not providing any support either given that the warranty expired 4 months ago.
Please understand that if it was a product <50€ that I used every day I wouldn't complain...but this is an expensive electronic equipment that I use sporadically (once a month max when travelling).
Given this is a clear hardware issue affecting hundreds of end-consumers, isn't Bose doing anything about it? Isn't there a Customer Support Service I can talk to in Europe? If Bose's position is to do nothing about it, please let me know so I can request support to the Spanish Consumer's Association (OCU).
I was a bit skeptical, but I can also confirm that I just talked to Bose Support (for US) and they are going to send me a replacement! It took about 30 minutes because I had to set up an account, give them the S/N, etc., but there were no issues. They will send a shipping label for me to return my current headset and then will ship me a new one, all free of charge.
I could not be happier with the outcome. Thanks BOSE!
(I do not work for Bose) This is a 'known' hardware issue (for over two years). Bose stated here in 2019 that it is not fixable by firmware. This is the only time I am aware of they have commented on it here. The contacts in the on/off switch are likely slipping. There is NO workaround. If this is indeed your problem you have two solutions: 1. Fix it yourself with DIY instructions here and elsewhere
2. Ask Bose for an exchange. For those out of warranty, they will initially offer the exchange for a price. Take it or not - your call. Those who have repeatedly called back and possibly escalated it report here eventually they will get to a representative that will be willing to do a free exchange, 'this one time'.
