All latches close doors, panels, and other surfaces. They differ in the way they close doors, panels, and other surfaces. A door lock over centre latch is also available. This means that your latch can lock to increase security.

Let’s first look at the various types of latches, before we present the best solution to your application.

1. Cam latches

These simple mechanical locks consist of a base and cam lever. Cam lock latch is sometimes referred to as this. It’s activated by turning the base using a key or another tool. This presses the doors and surfaces shut. There are many mounting options, including concealed or wings- and knobs. These can be ordered with T-Handles and a stainless steel cam lock. Cam latches are the most common cabinet latch hardware.

2. Compression latches

Although compression latches can be considered cam latches, they deserve their own spotlight. These latches seal tightly by compressing gaskets against the door and panel openings when they close. They are opened by a trigger release mechanism. The locking arm can be released by pressing a button or turning the key. Similar to cam latches, swell latches compress a type of vibration isolator known as a rubber bushing.

Fixed-compression latches allow you to have consistent compression and decompression at the desired depth. You can also choose adjustable compression lats that allow you to change the position of the locking cam. This allows you to adjust compression over time.

3. Slam latches

This latch is basically a spring-loaded latch. However, they are sometimes called push-to-close latches or have push lock fittings. Specially designed springs provide tactile resistance. The cam raises when the panel door is pushed. It then springs back behind the panel wall to lock doors and panels. This is a quarter-turn latch.

4. Draw latches

Also known as toggle latches or pull-down latches. The draw latch is made up of two parts. One side has an arm that clasps the other. The clasp combines the two pieces as the latch closes. It’s very simple. To close the surfaces, drawbars and pivot levers reach for catches. This seals the surfaces well, especially if there’s a gasket between them and the frame.

5. Slide latches

Sliding latches allow components to overlap. The actuation is done manually. Sliding snap latches, for example, require quick movement to catch the latch, which holds the surfaces closed and resists shock and vibration.

Solutions and Problems

Let’s now look at two common problems, and how latches can help.

1. Problem: protection against ingress

You might consider an outdoor electrical enclosure, an outdoor utility cabinet, or an outdoor telecom equipment case. These applications need to be protected against moisture, dust, and debris. The performance will be affected if this is not done. It’s not only the elements that you need to consider but also security.

Why compression matters

Compression latches increase the life of the equipment you are housing. Consistently compressing the gasket surrounding the enclosure opening will seal the gaps that would otherwise allow dirt, insects, or water in.

2. Problem: Vibrations and noise

Industrial machinery is often noisy due to HVAC system components and industrial generator parts. HVAC components, which include the rotating equipment, air, and fluid moving through pipes and ducts, can create vibration and noise. Vibration can lead to the loosening of mounting hardware, which can cause damage to the application.
