Keystone Electrical/Battery Clips

Keystone Electronics: Precision Battery Clips Built to Connect

When a reliable electrical connection between a battery and its host circuit is on the line, the quality of the clip or contact doing that work matters more than most people realize. Keystone Electronics has spent decades earning a reputation as one of the electronics industry's most trusted manufacturers of electrical and battery clips — and for good reason. Founded in 1950, Keystone Electronics Corp. established itself as a precision manufacturer of electronic interconnect components and hardware. Today, the company's quality system is ISO 9001:2015-certified , a credential that underscores its ongoing commitment to consistent, verified manufacturing standards.

The Industry's Broadest Battery Clip Selection

What sets Keystone apart in the battery clip and contact space is sheer breadth of coverage. Keystone's diverse selection of battery clips and contacts supports cylindrical battery cells including AA, AAA, AAAA, 1/2AA, CR2, CR123A, 2/3A, 1/3N, C, D, N, 9V, 12V, 18350, 18650, 20700, 21700, and 26650. Whether you're working with common alkaline cells or modern high-capacity lithium-ion formats, Keystone has a clip or contact engineered for the task.

Mounting flexibility is another area where Keystone excels. Their battery clips and contacts are available for a variety of mounting applications including surface mount, thru-hole mount, slide-in, and snap-on applications. This means engineers and technicians can find a Keystone solution regardless of the board design or enclosure type they're working within.

Design Variants for Every Application

Keystone doesn't take a one-size-fits-all approach. Their battery holder and clip offerings include surface mount battery clips and contacts, surface mount leaf-spring contacts, low-profile surface mount coin cell holders, positive and negative surface mount compact contacts, THM low-profile lithium and alkaline cell holders, and SMT low-profile lithium and alkaline cell holders.

For PCB and molded case applications, button, leaf spring, and coil spring battery contacts are available, providing a reliable connection while maintaining low contact resistance. Coil spring contacts are designed with a unique spring tension ability that accurately adjusts to variations in battery length — a small but critical detail that prevents intermittent connections in real-world use.

For snap-in applications, battery holders feature separate snap-on/snap-off connectors and incorporate reliable coil spring contacts that adjust to different battery lengths, assuring positive electrical connection along with low contact resistance.

RoHS Compliant and Built for Professional Use

Battery clips, contacts, and holders from Keystone are designed with leading-edge technology to accommodate all major manufacturers' batteries. All products in the line are RoHS compliant, making them suitable for regulated environments and modern electronics manufacturing. The battery holders feature polarized contacts with heat-resistant nylon housing and are suitable for many applications including photographic, medical, consumer, and industrial electronics.

For those with non-standard requirements, modifications as well as custom fabrications can be manufactured to meet special needs. That kind of application engineering flexibility makes Keystone a go-to partner for OEM designers who can't afford to compromise on contact reliability.
