  • Patent number: 6428059
    Abstract: A latch detector for automotive door locks is provided. The latch detector includes a detector body 1 having a recess 1a, a latch 4 rotating in the receiving recess 1a, a detecting switch 10 attached to the detector body 1, for detecting the latch 4 being in its full-latching position or the opening position and a detecting member 9 having a first arm 9c extending into the recess 1a to be engageable with a cam part 4c of the latch 4 and a second arm 9e exposing on the other side of the detector body 1. The detecting switch 10 is positioned on the other side of the detector body 1 so as to be operated by the second arm 9e of the detecting member 9. With this waterproof arrangement, it is unnecessary to construct the detecting switch by a waterproof and expensive element.
