Power button for a HP450 G3 laptop

[Zourous]

Anyone know a way to get hold of a spare one (maybe more) of these? If I look online, I just see options from America. Being hopeful I looked on HP's site and it doesn't look like they supply this sort of thing. What are you supposed to do if you get 3 or 4 power buttons failing from a batch of 90+ laptops that are now out of warranty. I know, i know, buy a new laptop.

I'm guessing it's just the tactile switch that has failed due to vigorous pushing ?

I can replace just the switches if you like ? No need to buy PCBs or new laptops

Thanks for the offer, but I don't think you want me contacting you everytime I get one of these.

You wouldn't need to contact me every time. Just post it/them with an SAE.

I'm not short of tact switches which weren't too expensive. I think it might be the ones on the left.

Actually I've just repaired one. I opened the laptop up and on this one found a small metalic dome which had moved out of positon of the switch contact. I just sellotaped it back in position and it's fine. On the other laptops this dome has obviously broken off and disappeared either inside the laptop and maybe even fallen out altogther. So I'm guessing I just need to purchase some tactile switches? Any ideas or hints on how I find the right sized one?

I measure with digital calipers but they tend to be standard size. RS has some but I get mine for Aliexpress as they are much cheaper.

Perhaps I could stick 5 in the post to you if they look to be the right size/style ?

Yes, from memory it is something close to 4mm. That would be very much appreicated if you could mail me some. I'll PM you my address.
