Performance Data Sheets

The key to designing and building reliable membrane switches is to qualify components, processes and design through testing. Nelson’s test lab has an ongoing testing program. Specific test reports for standard switch constructions are available for download.

Environmental Testing

Temperature and Humidity cycling is the best way of predicting long term reliability of switches that will be subjected to harsh operating conditions.

Life Cycle Testing

Our life cycle tester allows us to actuate a switch 1,000,000 times in less than a week. Life cycle testing is used to evaluate components and switch designs.
