DEADLATCH Meaning and
Definition
-
A deadlatch is a mechanism commonly used in locks and door handles to secure a door when it is closed. It is a specific type of latch that automatically engages when the door is closed, thus adding an additional layer of security to the door.
The deadlatch is typically installed into the edge of the door and engages with a strike plate attached to the door frame when the door is closed. It consists of a spring-loaded bolt mechanism that extends into the strike plate when the door is shut and retracts when the door is opened. The bolt is activated by turning the door handle or key, which compresses the spring and extends the bolt into place.
The purpose of the deadlatch is to prevent the door from being opened, even if the main lock is compromised or picked. It acts as a secondary locking mechanism that reinforces the security of the primary lock.
Deadlatches are often used in residential, commercial, and institutional buildings to enhance security and prevent forced entry. They are particularly effective for external doors, as they provide an additional barrier against break-ins.
In summary, a deadlatch is a type of latch that automatically engages when a door is closed, increasing its security. It reinforces the primary lock and prevents unauthorized access, making it an essential component in door security systems.

Etymology of DEADLATCH
The word "Deadlatch" is a combination of two components: "dead" and "latch".
1. "Dead": The term "dead" in this context refers to something that is not alive or inactive. It is derived from Old English "dēad", meaning lifeless or deceased, which further traces back to Proto-Germanic "dauþaz".
2. "Latch": The word "latch" refers to a device used to secure a door or gate. It comes from Middle English "lacche", which was derived from Old English "læccan", meaning to seize or grasp.
Therefore, the etymology of "Deadlatch" can be understood as a latch mechanism that is inactive or immovable without external manipulation, often used for added security purposes.
