There's a spring on my pcb, is it alright if I just cut it off?

I was wondering if it’s safe to cut this spring off the pcb, probably could help remove the pingy noise but I’m not sure what the purpose of this is and unsure if I should remove it

Can’t tell for sure, but it may be for grounding purposes.
When assembled, does that spring make contact with a metal part?
Like the case or the switch plate?


It touches the plate, and it says “T1” above the spring on the pcb

When I zoom in the picture it looks as if the spring is connected to the ground plane of the pcb.

That and that it touches the plate would confirm that it’s for grounding purposes.

I personally would not remove it.


Lube it :crazy_face:

Change it to a progressive spring :face_with_monocle:


Nah we need a triple stage spring here… :laughing:

Now take a generous amount of lube and twirl it around the curls. It doesn’t matter too much if you see the whiteness of the lube in the spring because it tends to be more forgiving than other parts.

I ran out of krytox…

It doesn’t make sense to me why the the PCB would ground to the case if the case itself isn’t grounded. If anything, the best path to ground would be over the USB cable. Hopefully someone more knowledge than me can explain this.

I assume the ground plane of the pcb is connected to the shielding of the usb-connector.
And by that the plate, which the spring touches, is also connected to ground.

All that probably due to esd-considerations.
