Disc Drive switch (KSB-004) broken

Hello,

So one of the two switches towards the back of the disc drive broke. Now it won’t recognize that there is a disc in or recognize that one is being inserted. I manually fed a disc in by utilizing the manual screw but it won’t spin or recognize that there is a disc in. Is there a place to purchase strange pieces like this or would I need to purchase another PS4/disc drive? Thank you.
