Abstract

The invention provides a closure latch assembly with a child lock having an asymmetrical toggle spring arrangement. The latch assembly is provided with a child lock mechanism having a spring system including a first spring member and a separate second spring member that requires a first force to move the child lock mechanism from an off position to an on position and a second force to move the child lock mechanism from the on position to the off position, wherein the required second force is greater than the required first force, thereby indicating to a user by tactile feedback the relative position (on / off) the child lock mechanism is in, thereby assuring intended movement of the child lock mechanism from one of the on / off positions to the other.
