What do developers need to know about Membrane Keyboards?

Invented over 30 years ago, membrane keyboards and switches were at first ridiculed as a low-cost but unreliable input technology. However, after decades of improvements, the membrane switch has now been established as an effective option for many different technical applications.

What is the history of membrane keyboards, how does their technology work, and what should device and system developers be looking for when deciding which membrane keyboard technology they should use for their projects?

This short white paper also covers advanced topics such as optical bonding, key dome layering, and capacitance touch technologies.
