Broken LT trigger Replacement parts

The little component of the circuit board which is activated by the LT trigger is constantly activated. I disassembled it and found all the mechanical functions of my LT button we’re in good shape. So I narrowed it down to the the component on the circuit board it was attached to. I was hoping to replace this component since it seem to be faulty, but when I looked online my problem seemed to be a one off thing. I then tried looking a circuit board diagrams for the part number. Didn’t find a good one for identifying the part. I was hoping someone here would be able to point me in the right direction to replace this part without replacing the entire mother Board.
