Looking for a switch
Potter & Brumfield #W67A2013-3
Are you sure this is the part number? I don't see this item on Grainger or on Potter & Brumfield; TE Connectivity.
Grainger may have this switch, they sell this brand, check the part number, if you don't have it, go to your close Grainger store, show it, they will find it or one equivalent on other brand.
