Snap Together Enclosures

Snap together cases provide a quick and convenient plastic utility box solution for electronics. Browse small to medium-sized snap-fit utility boxes for indoor applications. Made from impact-resistant ABS, the durable all-plastic design is ideal for those seeking metal-free applications to prevent interference.

The snap-together fit ensures easy, toolless assembly. Designed to hold small PCBs, the cases are also useful as a potting box. Read more below to learn about snap-fit enclosures and Polycase’s snap enclosure offerings.

How Does a Snap Fit Enclosure Work?

Indoor electronics applications often require enclosures that are easy to assemble, cost-effective and provide reliable protection. Snap-together enclosures offer all of these qualities, which is why they’re popular as general-purpose indoor electronics enclosures and potting boxes. 

The mechanics of a snap-fit enclosure are simple. Each enclosure is built with molded snap-fit joints that allow the box’s lid to snap onto its base. Assembly is simple, fast and clean. Just connect the snap inserts on the base and lid to create a secure hold, with no tools, glue or fasteners required. 

Snap-fit enclosures can have other benefits as well. A snap-fit assembly eliminates the need for metal fasteners in the enclosure, which can help reduce the chance of interference with the electrical components inside. In addition, many snap-on designs make the enclosure simple to open when access to the components is required.

Finally, snap-fit enclosures are a common choice for potting boxes, since many potting boxes require a lid that’s easy to attach. Rather than a potting box with a glue-on lid, some device builders opt for the simplicity of a snap-fit enclosure. See our guide to choosing a potting box for more information. 

Snap Together Enclosures from Polycase

Whether you’re building a DIY electronics project or a consumer device, using a snap-fit case can be an excellent option. Polycase’s selection of snap-fit enclosures offers a full range of tough and affordable ABS boxes built to protect your electronics. 

Our enclosures’ snap-fit design also offers a convenient method for mounting a printed circuit board. Simply position your PCB over the enclosure’s mounting boss standoffs and then snap the pieces of the enclosure together, capturing the circuit board and providing a secure hold.

In addition to our popular general-purpose snap-together models, we offer snap-fit enclosures with form factors for specific applications, including key fob and thumb drive enclosures. Some models offer even more features, including optional buttons on our key fob enclosure models.
