Hi, had the same problem. After market micro switch replacement for Hitachi NR 90GC from RS Components Stock number 682-1888 MPN; D2HWC203MR.
Note; this requires soldering in with heatshrink and cutting flyleads to correct length. Part of the alignment issue can be the handle screws working loose over time with use. Don't force anything back when assembling and use a little grease on contact parts.
