Abstract:
An automotive closure latching system comprising:a first rotary latch (10) for releasably locking a first closure; said first latch having a locking position and a release position; said first latch having a first cam surface;a first electric switch (18) having an actuator engaged with said first cam surface so that when the first latch is moved to the release position, said first switch is operated by said cam surface to a circuit-closed condition;a second rotary latch (26) for releasably locking a second closure; said second latch having a locking position and a release position; said second latch having a second cam surface;a second master control electric switch (42) in series connection with said first switch; said second switch having an actuator engaged with said second cam surface so as to be in a circuit-open condition when said second latch is in its locking position; said second cam surface being effective to operate said second switch to a circuit-closed condition during initial movement of said second latch toward its release position; andan electro-magnetic means (32) for releasing said second latch; said release means being in series connection with said first and second switches so that said release means is electrically energized only when both switches are in the circuit-closed conditions; said release means having a plunger (36) movable from a latch-obstructing position to a non-obstruct position only when said release means is energized, whereby said second latch can be moved to its release position only when the first switch is in the circuit-closed condition.
