Industries served

LID components are used in medical devices, industrial controls and instrumentation, automotive electronics, home appliances, telecommunications equipment, test and measurement devices and consumer electronics. Many of these markets need reliable, long-life interfaces that are easy to clean, and LID designs each part around the customer's operating environment, user experience and regulatory needs.

Quality and certifications

Quality management is central to the company's operations. LID holds ISO 9001 (quality management), ISO 13485 (medical devices), IATF 16949 (automotive) and ISO 14001 (environmental management) certifications. These systems support traceable, repeatable production for customers in regulated industries such as medical and automotive.

Engineering and customization

Most LID products are custom-built. The engineering team works from customer drawings, samples or ideas to develop the right structure, materials, graphics and electrical layout. Customers can choose key layouts, tactile force, printing colours, surface textures, backlighting, adhesives and connection methods. Rapid prototyping lets customers test and validate designs before they move to volume production.

Flexible ordering

LID has no minimum order quantity, so engineers and buyers can order prototypes, small pilot runs or high-volume production from the same supplier. This flexibility helps start-ups, design houses and established manufacturers alike.
