Elastomer Keypads

Elastomer keypads offer a high-profile, tactile feel with an underlying switch layer. Boyd’s elastomer keypads exhibit excellent weatherability in ruggedized environments, moisture and chemical resistance, and temperature endurance between -30° C to +80°C. Keypad interfaces provide users with an exceptional tactile response and customizable tactile feedback, tailored between 100 g to 300 g of force. Elastomer keypads are an excellent choice when three-dimensional keys are needed in high-moisture environments such as marine or defense settings.

Design flexibility

Available in a wide range of design possibilities with custom colors, finishes and backlighting options

Longer Product Lifetimes

With excellent weatherability in ruggedized environments, elastomer keypads with durable Boyd construction are resistant to moisture, chemicals, and can endure temperatures ranging between -30° C to +80°C.

Enhanced user interaction

Provide users with exceptional tactile response with customizable tactile feedback with elastomer keypads that can be tailored between 100g to 300g of force.


Backlighting is an industry standard to augment the functionality and aesthetics of a device. Adding backlighting to your product improves visual appeal and defines your brand’s distinctive style. Backlighting guides users and provides feedback during device operation, especially in darker settings. From user interface assemblies to branded nameplates, Boyd helps with design considerations and provides the right integrated backlighting solution for your program.

Membrane Switches and Keypads

A membrane switch is a micro-motion, momentary contact, flexible circuit with a printed graphic overlay, ideal for industries such as medical and industrial equipment.  Offering easy cleanability, membrane switches are resistant to moisture, chemicals, and abrasion. With custom colors, textures, backlighting, and tactile response options, Boyd provides complete customization from from membrane switch panel design, manufacturing, and assembly support.

Superior Durability

Offering easy cleanability, membrane switches are resistant to moisture, chemicals, and abrasion.

Design Flexibility

With custom colors, textures, backlighting, and tactile response options, membrane switches offer a wide range of design configurations.

Capacitive Touch Sensors and Switches

Replace mechanical buttons with elegant, non-tactile, compact user-interface with capacitive switches, eliminating several design layers and components from the traditional switch circuitry. Capacitive switches are thin, non-mechanical designs applied to curved surfaces and mounted behind glass or decorated plastic. Depending on your application requirements, these sensors can also be backlit to provide a cost-effective modern design. Boyd offers a variety of printed capacitive sensors that can integrate with commonly available microcontrollers to provide capacitive touch sensing.

Sleek and Contemporary Designs

Replace mechanical buttons with elegant, non-tactile, compact user-interface

Superior Durability

Prolong switch and device life with sealed, smooth, and easily cleanable capacitive switches, which prevent ingress of moisture or dust.

Design Flexibility and Enhanced User Experience

Integrate different input methods and feedback mechanisms, adding another layer of communication with the end-user and improving usability.

User Interface Printed Circuit Boards (PCBs)

Printed circuit boards (PCBs) provide a simple way to reduce materials and interconnects by eliminating the need for a rigid subpanel. Boyd can help you combine PCBs with other switch solutions such as keypads, backlighting, and display screens to create the ideal user interface for your application. We offer complete user interface PCB manufacturing services including circuit board stack-up, design support, prototyping, and fabrication.
