What part type is denoted by SKx?

I’m fairly well versed in component labels like C1, R12, U72, etc but while taking apart a small external hard drive I found a component which looks to be made of ceramic labelled SK1.

Now, crystals should be marked as Yx (where x is a number) and both ends seem to terminate at a chip, but is this a standard part label? Other oscillators on the board are labelled as you’d expect.

  Some varistor perhaps? Can you zoom out a bit and follow the trace to the left?

  Please see our Component Identification Question Guidelines. As it stands, your question currently does not meet several of the requirements. Please take another picture that's in focus!

  Thanks folks! I’ve already thrown out the PCB so not much luck. I hadn’t expected to learn exactly what part this is in question, but what part type is denoted by “SK”. Sorry if the photo started a goose chase. For what it’s worth, both leads fed back to the IC through R4 and R53.

  I'm voting to close this question as off-topic because the asker has thrown away the component in question and thus it is not available for further investigation.

  It's not an identification question. It's a perfectly fine question about PCB layout and best-practices naming.

while taking apart a small external hard drive I found a component which looks to be made of ceramic labelled SK1

It's a shock sensor used by the hard drive controller (hence the choice of "SK" for the designator makes sense - ShocK).

Notice that it is mounted at an angle on the PCB, unlike the other components. That is not "just for fun", but is done to make it sensitive in both X & Y planes.

For example, here is the product page for this type of ceramic shock sensor, made by Murata:

https://www.murata.com/en-eu/products/sensor/shock/consumer

Quoting from that web page:

Murata shock sensors find use in many computer hard disk drives. They detect impacts - for example, when the storage falls to the floor - in a fraction of a second and prevent read and write errors.
