摘要

Over spray sensor for an injection molding machine comprises a mobile housing (14, 16) which is attached to the mold. This is compressed against the effect of a biasing spring (22) by an Over sprayed plastic to activate a contact (12). A second spring (18) holds the contact in a central position. Contact is produced both by axial and sideways movement of the contact section.
