A car door latch is a crucial component that ensures the safety and security of vehicle occupants by keeping the car doors securely closed while driving. It also allows for easy opening and closing of the doors, providing convenience and accessibility.
How Does a Car Door Latch Work?
A car door latch is a mechanical device that engages with a striker on the car’s body to keep the door shut. When you pull the door handle, it releases the latch, allowing the door to open. The latch mechanism consists of several parts, including:
- Latch Assembly: This is the main component that connects with the striker.
- Striker: A metal piece attached to the car frame that the latch hooks onto.
- Door Handle: The part you pull to release the latch.
- Locking Mechanism: Prevents the latch from being released when the door is locked.
