The interface starts outside the switch
Housing dimensions, locating features, clips and connector keying determine whether the part can be installed correctly. A near match can still create loose mounting or an incompatible harness connection.
Internal construction supports the function
Contacts, conductive parts, springs and operating mechanisms must work together for the selected switch function. Repeated cabin use makes tactile consistency and contact performance important purchasing considerations.
Housing and mounting geometry
Connector keying and terminal alignment
Contact material and surface condition
Spring and rocker mechanism
Illumination components where applicable
Evaluate the complete reference
Do not judge construction from one isolated material claim. Review fitment, operating feel, electrical function and the agreed inspection plan against the exact model.
