ABSTRACT:
A vehicle door latch device comprises a latch engageable with a striker, a ratchet engageable with the latch, an open lever for releasing the ratchet from the latch so as to open the door, a lock lever displaceable between a locked position and an unlocked position, an actuator for changing over the lock lever, a switch adapted to be turned on when the latch comes into a full-latch position by the engagement with the striker, and a housing. The housing has a passage into which the striker enters, a first space for receiving the latch and the ratchet, a second space for receiving the actuator. The first space is substantially communicated with the outside through said passage, and the second space is substantially isolated from the passage so as to be sealed. The switch is attached in the second space so that a movable terminal of the switch is protruded into the first space.
