When we think about technology invented over 30 years ago, the assumption is that it’s now outdated and possibly obsolete. VCRs, answering machines, and 8-bit video game consoles come to mind. However, one technology that has stood the test of time is the membrane switch. Introduced in the early 1980s, membrane switches were quickly adopted by many industries, including medical equipment. Since then, materials and converting processes have greatly improved, making membrane switches even more functional and cost-effective. Today, membrane switches are the go-to interface for many types of medical devices – from patient monitoring systems to hospital beds to surgical equipment.
