Magnetic switch for starter, has external sections extending from resin cover, which are coupled by screwed nut and gap between sealing areas of anchorage head and cover is sealed by O-rings

摘要

A resin cover (25) encloses the switch, through metallic fastening sections. The sealing areas (262b) of anchorage head engage with respective sealing areas of the cover, by screwing nut over screws (261b). Based on the axial force generated between nuts and head, external sections of cover are coupled. The gap between the sealing areas is sealed using O-rings. The external sections extend from the metallic sections such that external section are coupled, when nuts are screwed over the screws. A rotation stop section extends from the anchorage head. Sealing areas of both head and cover are arranged in parallel relation.
