What Do You Know About Latches? How Many Types Are There?

Latches are closing mechanisms used on many doors, including interior, outdoor, sliding, swinging, cabinetry, and more. Latches are intended for regulated action of opening and shutting doors and enabling a secure connection. 

Most homes, workplaces, industrial settings, and structures that employ conventional doors have some version of a door latch. Additionally, similar mechanisms are used in the auto sector for automobile doors, compartments, and various domestic products.

Applications of Latches

Indoor Latches

In general, the standards for indoor applications are less stringent than those for outdoor applications, so you don't have to worry about environmental repercussions. You might choose locks made of zinc or plastic, both of which are more reasonably priced options, to keep the whole cost within your financial constraints. 

In addition, the degree of security required for interior applications is likely lower than that needed for exterior applications. You have the option of selecting non-locking latches for the internal environment. 

However, this will depend on the access control needs that are necessary. However, you might consider alternatives with a locking mechanism to ensure that only authorized individuals have access.


Outdoor Latches

The requirements and regulations that outdoor latches must meet are often significantly more stringent than those that apply to interior latches. It would help to consider all environmental aspects, such as the severe humidity, ice, and weather.

Because stainless steel latches are resistant to corrosion and won't suffer any deterioration when exposed to the weather, this might be a significant factor in deciding the kind of latch you need.

In addition to water and dust infiltration compliance regulations and standards, there may be other rules and standards that must be satisfied depending on the business. For example, latches used in electrical and food processing equipment could be required to fulfill the specific design, construction, or sealing requirements. 

The overall performance of the equipment may be improved with latches that meet these standards since they will prevent mechanical and electrical systems from being disrupted by elements such as water and dust. However, water and dust aren't the only things that can get into the contents of your cage. Other things, such as animals, may also get in there.




Types of latches

The range of locks available seems to be rather broad, with the differences stemming from the complexity of the latches and the functions they serve. When examining the needs of their designs, engineers, technicians, and end-users should carefully analyze the many kinds of latches available. 


There are several kinds of latches, each of which can fulfill the needs of a distinct set of designs and applications. The following are the most typical varieties of latches:

Latches with Cams

A body usually linked to the cabinet door and a cam lever attached to a door opening are the two components that make up a cam latch. Cam latches are simple mechanical devices that are also cost-effective. 

A motion equal to one-quarter of a turn is required to activate the mechanism. This causes the cam beneath the door frame to revolve, which locks the door. You may further limit access to unauthorized employees by selecting a cam-lock, an essential quarter-turn latch with a locking mechanism. 

Their primary use is to keep enclosures and cabinets closed, but they can also be used to keep doors closed.


Compression Latches

A compression latch is, in all practicality, a cam latch, although in one of the numerous shapes that cam latches may take, it is made up of both the base and the cam lever. The most apparent difference, however, is that they are engineered so that the gasket is compressed against the doors and panel holes that they are responsible for securing, ensuring a secure seal.

Compression locks are an excellent choice for applications that must fulfill specific environmental standards. The compression of the gasket protects against dust, moisture, and even vibration thanks to its sealing properties. T-handles or locks operate these cam latches, just as regular cam latches.

There are two unique kinds of compression latches, namely adjustable compression latches and fixed compression latches. The first method maintains a constant level of compression over time, but the second allows you to adjust the level of compression and decompression progressively.


Slam Latches

A slam latch is a kind of spring-loaded latch with a separate component with a notch or a curve and an enclosed spring mechanism with a sliding bolt pushed by the spring. The design of a slam latch is similar to that of a regular latch. One pin or the notch is bent, which restricts the hook's movement to just one particular direction.

When the door is pushed, the pin slides over the notch, and the spring pulls it out at an angle that prevents it from sliding back in, therefore locking the door. When the door is closed, the pin cannot slide back in. The door may typically be opened by manipulating a knob, a door handle, or some form of the lever that unwinds the spring and releases the tension in the door's hinges.

In addition, they are available in a number of sizes, ranging from light-duty latches used on cabinet doors to heavy-duty latches installed on the doors of cold storage facilities. For an added layer of protection, the latch may be fitted with a lock that requires a key.


Pull the Latches

Drawing latches, also known as toggle latches, are secured by using tension to attach two surfaces on the same plane. This kind of latch typically consists of two different sections: the first is the working mechanism, which is connected to one of the surfaces, and the second is the fastening mechanism, which is coupled to the other side. 

Tension is produced whenever the working mechanism's lever is moved to the position where it can hook onto the securing mechanism. Most applications for these include engine hoods, and toolboxes because of their ease of installation, low cost, and capacity to provide an adequate level of compression, sufficient to mitigate any little vibrations.


Sliding Latch Mechanisms

Standard sliding latches, often known as bolt latches, are the types of back gate latches that consist of a fixed keeper and a sliding and rotating bolt. Sliding latches are also sometimes referred to as bolt latches. The assembly is made secure when the sliding or rotating bolt slides behind the stable component. 

The two sections are fixed on fastening surfaces, such as doors and frames, which make the assembly fast. In most cases, manual operation is required to activate the device. Despite their ease of installation and usage, they do not provide much protection, which is reflected in the reasonable cost of these products. 

Nevertheless, it is essential to bring to your attention that sure sliding locks are fitted with a spring that allows automatic bolt extension.



A hasp is an essential, easy-to-install, operates latch composed of a strap and a staple. Hasps depend on padlocks for additional security and consist of a simple belt and staple. On one end of the strap is a metal plate with a slot that fits over the nail, and on the other is a hinge that enables it to swing while connected to a surface. 

The strap is held in place by the staple. The second staple component is a loop made from a bent metal rod or a formed plate. This component is also known as the staple. A pin is inserted into the staple's loop to secure the strap. Alternatively, a padlock may be used if the situation calls for increased safety.


Door Latches That Use Magnets

Magnetic door latches, referred to as door catches, are two-part systems consisting of a permanent magnet and a ferromagnetic striking plate. Door catches are another name for magnetic door latches. They are used to offer an easy latching mechanism for the doors of furniture or light-duty doors that see little usage. 

If you'd want an extra precaution, you might choose to install an electromagnetic door lock.
