What is a Compression Latch?

[pysong]

A compression latch is essentially a cam latch, in any of its various forms, consisting of both the base and the cam lever. However, unlike traditional cam latches, compression latches compress gaskets against doors and panel openings when they close, thus providing a tight seal. As such, they're fantastic for applications in specific environmental requirements, like protection against moisture, rain, water, dust, or even vibration and electrical interference.Get more news about compression latch,you can vist our website!

Similar to regular cam latches, compression lathes can also feature a T-handle or even a locking mechanism to prevent unauthorized use. There are two types of compression latches: fixed compression latches with fixed cams that provide consistent compression and adjustable compression latches that work similarly to typically adjustable cam latches. The latter, however, allows you to adjust the compression and decompression over time.

How Does a Compression Latch Work?
Compression latches work on the same principle as typical quarter-turn cam latches. As such, they're a reliable solution to hold the doors and panels shut while simultaneously offering protection from water, dust, vibration, and even electromagnetic interference, in enclosures that require such measures.

We can actuate the compression latch by tuning its base with a key, a cam lever, a T-handle, or any other type of quick-action fastening device. By compressing the gasket surrounding the enclosure opening with consistent force, we're closing all the gaps that would otherwise allow dirt, water, or even insects inside.
As seen in the video, there are two types of compression latches suitable for different applications. Heavy-duty applications might require a compression toggle latch, which provides higher latching forces and lower operating effort. On the other hand, moderate and lighter applications don't require large amounts of compression, so a regular actuation by a handle, button, or key locking should do the trick.

We suggest compression latches with a fixed cam for precise and quick installations, which is often the ideal solution. They require no adjustments and provide minimal intrusion into the space that is being sealed.

In contrast, applications with greater variances require the use of compression latches with adjustable grip range. These are adjusted according to the application and the required compression while offering compensation for various tolerances, reducing long-term management and maintenance costs.

One last factor you should consider is accessibility. Enclosures that are accessed frequently and by hand usually require non-locking latches that feature T-handles, knobs, or levers such as flush triggers as operating mechanisms.

However, secure environments may require limited access to authorized personnel only. For example, a simple compression latch equipped with a locking mechanism that requires a key or a special kind of tool to operate might be necessary.
