The paddle latch refers to a specific type of handle feature that is pulled outward to fasten or unfasten two adjacent surfaces. Paddle latches are common in forestry, mining, agricultural and construction industries for gates, doors and tool and utility boxes as they are sturdy and reliable.
Paddle latches are distinct from other types of latches by the handle feature that is used to fasten or unfasten the latch. Common in forestry, mining, agricultural and construction industries for gates, doors, tool and utility boxes and other heavy duty applications, paddle latches are a durable latching option. Latches are mechanical joining devices designed to be used with two adjacent components to secure their closure. Most industrial latches are simply composed of two panels attached to the two adjacent components with a pin or bar used to connect the two by sliding through a notch or loop. Paddle latches are constructed in a similar style to bolt latches and are generally contained within a panel. This is used to secure the latch and is flush with the surrounding surface, allowing the paddle latch to be used in limited space applications, or for those applications which require minimal protrusions to prevent operational hazards. Paddle latches are typically composed of the same basic structure of other types of latches and additionally incorporate a handle into the latching mechanism. They can also be designed with a locking mechanism for increased security.
The handle of a paddle latch is typically a thin, rectangular or rounded sheet of metal or plastic housed by a recessed plate. A second panel, or plate, is attached to the adjacent surface and contains the notch or groove necessary for the pin to connect to. A spring loaded pin activated by using the handle is responsible for engaging and disengaging the latch by pushing the pin into the groove or notch on the adjacent plate. When the handle is pulled outward it recoils the spring attached to the pin and releases the latch. As paddle latches are required to be durable, steel and stainless steel are the most common materials used to construct these latches, though some smaller variations of paddle latches are made with high strength thermoplastics such as polyetherimide. As they are a durable latching option, paddle latch mechanisms are often incorporated into slam latches which are required to withstand regular impact and high tension. Paddle latches are generally housed largely by the panel in which they are installed and are manufactured through the processes of casting and forging for metal paddle latch components, and by injection molding for plastic latches. Type of material used is dependent on the application for which the latch will be employed and the stress and strength requirements of that applications.
