With custom colors, textures, backlighting, and tactile response options, membrane switches offer a wide range of design configurations.
Offering easy cleanability, membrane switches are resistant to moisture, chemicals, and abrasion.
A membrane switch is a micro-motion, momentary contact, flexible circuit with a printed graphic overlay. Boyd provides complete user interface custom manufacturing, design and engineering support, and sub-assembly for membrane switch panels. Versatile and economical, membrane switches are ideal for industries such as medical and industrial equipment because they are easy to clean with no moisture ingress. They also offer thin design options coupled with nearly endless membrane keypad configurations.
