Aircraft Part Piper 20611L-88-533 Switch

This item was purchased from an aviation surplus sale. I do not know the history of it. It is in good cosmetic condition. It is marked, "AR, PA-31T-138, C-GNWD". The plunger part of this switch feels like it I working fine. I am not able to test it electrically. It only comes with what is shown in the pictures.
